What is the slope-intercept form equation for a line?

The slope-intercept form equation for a line is y = mx + b, where y represents the y-coordinate, x represents the x-coordinate, m is the slope of the line, and b is the y-intercept, which is the point where the line crosses the y-axis. This form is commonly used in algebra and graphing to represent linear equations.

What does the slope of a line represent?

The slope of a line represents the rate of change of the line, or how steep the line is. It shows how much the y-axis values change for a given change in the x-axis values. A positive slope indicates an upward direction, a negative slope indicates a downward direction, and a slope of zero indicates a horizontal line.

What does the y-intercept of a line represent?

The y-intercept of a line represents the point at which the line intersects the y-axis on a graph. It is the value of the y-coordinate when x is equal to 0. The y-intercept can provide information such as the initial value of a function or the starting point of a relationship between two variables.

How can you determine the slope of a line given two points?

To determine the slope of a line given two points, you can use the formula: slope = (change in y-coordinates) / (change in x-coordinates). First, find the difference between the y-coordinates of the two points (y2 - y1) and the x-coordinates (x2 - x1). Then, divide the change in y-coordinates by the change in x-coordinates to calculate the slope of the line passing through the two points.

How can you determine the y-intercept of a line given its equation?

To determine the y-intercept of a line given its equation, you can look at the equation in slope-intercept form, which is y = mx + b. The y-intercept is represented by the term b in the equation. Therefore, the y-intercept is the value of y when x is equal to 0. By setting x to 0 in the equation and solving for y, you can find the y-intercept of the line.

How can you graph a line using the slope-intercept form equation?

To graph a line using the slope-intercept form equation (y = mx + b), first identify the y-intercept (b) as the point where the line intersects the y-axis. Plot this point on the graph. Then use the slope (m) to find a second point by moving vertically (up or down) according to the value of the slope and horizontally according to the value of the slope divided by the coefficient of x. Connect the two plotted points with a straight line to graph the line.

What does a positive slope indicate on a graph?

A positive slope on a graph indicates that as one variable increases, the other variable also increases. This means that there is a positive correlation between the two variables, showing a direct relationship between them.

What does a negative slope indicate on a graph?

A negative slope on a graph indicates that the relationship between the two variables being graphed is a negative correlation. In other words, as one variable increases, the other variable decreases. This means that the line on the graph slopes downwards from left to right.

How do you determine if two lines are parallel or perpendicular using their slopes?

Two lines are parallel if their slopes are equal, meaning they have the same rate of change. Two lines are perpendicular if the product of their slopes is -1, indicating that they intersect at a right angle. Therefore, to determine if two lines are parallel, calculate the slopes of the lines and check if they are equal. To determine if two lines are perpendicular, calculate the slopes and multiply them together to see if the result is -1.

How can you find the x-intercept of a line given its equation?

To find the x-intercept of a line given its equation, one can set y equal to zero in the equation and then solve for x. This is because the x-intercept is the point where the line intersects the x-axis, meaning the y-coordinate would be zero. By substituting y with zero in the equation and solving for x, you can find the x-coordinate of the x-intercept.
