What are the steps to graph a linear equation?

The steps to graph a linear equation are: 1) Plot the y-intercept by locating where the line intersects the y-axis, which can be found by setting x=0 in the equation; 2) Determine a second point by using the slope of the line, which is the coefficient of x in the equation (usually in the form y = mx + b); 3) Connect the two points with a straight line to complete the graph.

How do you determine the slope of a line from its equation?

To determine the slope of a line from its equation, you need to put the equation in slope-intercept form, which is y = mx + b, where m represents the slope of the line. Once the equation is in this form, the coefficient of x will give you the slope of the line. If the equation is not in slope-intercept form, you can rearrange it to isolate y on one side and then identify the coefficient of x to find the slope.

What does the y-intercept represent on a graph?

The y-intercept on a graph represents the point where the graph intersects the y-axis. It signifies the value of the dependent variable (y) when the independent variable (x) is 0. In other words, it is the initial value of the function at the start of the graph.

How do you find the x-intercept of a line algebraically?

To find the x-intercept of a line algebraically, set y to 0 in the equation of the line and solve for x. This is because the x-intercept is the point where the line crosses the x-axis, meaning the y-coordinate is 0 at this point. By substituting y with 0 in the equation of the line and solving for x, you can determine the x-coordinate of the point where the line intersects the x-axis.

How can you determine if two lines are parallel or perpendicular?

Two lines are parallel if they have the same slope, meaning they have the same steepness and do not intersect. To determine if two lines are perpendicular, you can calculate the slopes of the lines and check if the product of their slopes is -1. If the product is -1, the lines are perpendicular, meaning they intersect at a right angle.

What is the difference between a positive and negative slope?

A positive slope indicates that as one variable increases, the other variable also increases. In contrast, a negative slope denotes that as one variable increases, the other variable decreases. Positive slopes point upwards from left to right on a graph, while negative slopes point downwards from left to right.

How does the graph of a vertical line differ from the graph of a horizontal line?

The graph of a vertical line is a straight line that is perpendicular to the x-axis, where all points on the line have the same x-coordinate but varying y-coordinates. In contrast, the graph of a horizontal line is a straight line that is parallel to the x-axis, with all points on the line having the same y-coordinate but varying x-coordinates. Vertical lines have undefined slopes, while horizontal lines have slopes of zero.

What is the significance of the slope-intercept form of a linear equation?

The significance of the slope-intercept form of a linear equation, y = mx + b, lies in its ability to provide key information about the line it represents. The slope, m, indicates the rate of change of the line, while the y-intercept, b, represents the value of y when x is zero. This form makes it easy to identify the slope and the y-intercept, enabling quick graphing and analysis of the linear relationship between variables. It is a powerful tool in understanding the behavior of linear functions and is commonly used in various fields such as mathematics, economics, and science.

How can you find the equation of a line given two points on the line?

To find the equation of a line given two points on the line, you can use the point-slope formula. First, calculate the slope of the line using the two points (m = (y2 - y1) / (x2 - x1)). Then, pick one of the points to use in the formula y - y1 = m(x - x1) to find the linear equation of the line. Substituting the slope and one of the points into the formula will give you the equation of the line in the slope-intercept form.

How does changing the coefficients in a linear equation affect the graph?

Changing the coefficients in a linear equation affects the slope of the line on the graph. If the coefficient of x changes, the line becomes steeper or flatter, depending on whether the coefficient is increased or decreased. If the coefficient of y changes, the line shifts up or down on the y-axis. Ultimately, changing the coefficients alters the angle and position of the line, resulting in different slopes and intercepts on the graph.
