What is slope-intercept form?

Slope-intercept form is a linear equation written in the form y = mx + b, where m represents the slope of the line and b represents the y-intercept, which is the point where the line crosses the y-axis. This form is commonly used in mathematics and allows for easy identification of the slope and y-intercept of a line.

How do you write an equation in slope-intercept form?

To write an equation in slope-intercept form, start with "y =" followed by the slope of the line "m" multiplied by the variable x, then add "+ b" where "b" represents the y-intercept of the line. The equation will look like: y = mx + b. This form makes it easy to identify the slope and y-intercept of the line just by looking at the equation.

What does the slope represent in slope-intercept form?

In slope-intercept form (y = mx + b), the slope (m) represents the rate of change of the dependent variable (y) with respect to the independent variable (x). It shows how the y-values change for a unit change in x. A positive slope indicates a positive relationship where y increases as x increases, while a negative slope indicates a negative relationship where y decreases as x increases. Additionally, the slope also represents the steepness of the line on a graph.

How do you determine the slope from a given equation in slope-intercept form?

To determine the slope from a given equation in slope-intercept form, simply look at the coefficient of the variable (usually x) that is not being multiplied by the y-intercept constant. This coefficient represents the slope of the line. If the equation is in the form y = mx + b, where m is the slope and b is the y-intercept, then the value of m is the slope of the line.

What does the y-intercept represent in slope-intercept form?

The y-intercept in slope-intercept form (y = mx + b) represents the point where the graph of the equation crosses the y-axis. It is the value of y when x is equal to 0, or the initial value of the function before any changes in x.

How do you determine the y-intercept from a given equation in slope-intercept form?

To determine the y-intercept from a given equation in slope-intercept form (y = mx + b), simply look at the constant "b" term. This term represents the y-intercept and tells you the point where the graph intersects the y-axis. So, the value of "b" in the equation is the y-intercept.

How do you graph an equation in slope-intercept form?

To graph an equation in slope-intercept form (y = mx + b), start by identifying the y-intercept (b) on the y-axis. Then, use the slope (m) to find a second point by moving up or down and right or left from the y-intercept with the given slope. Connect these two points with a straight line to graph the equation. Repeat the process if needed to identify more points and accurately plot the line on the coordinate plane.

How do you determine if two lines in slope-intercept form are parallel?

Two lines in slope-intercept form are parallel if they have the same slope. In slope-intercept form, a line is represented as y = mx + b, where m represents the slope of the line. If two lines have the same slope, then they are parallel.

How do you determine if two lines in slope-intercept form are perpendicular?

To determine if two lines in slope-intercept form (y = mx + b) are perpendicular, you can examine their slopes. If the slopes of the lines are negative reciprocals of each other (i.e., the product of their slopes is -1), then the lines are perpendicular. In other words, if the slopes of the two lines are m1 and m2, then m1 * m2 = -1 indicates that the lines are perpendicular.

Can any linear equation be written in slope-intercept form?

Yes, any linear equation can be written in slope-intercept form, which is in the form of y = mx + b, where m is the slope of the line and b is the y-intercept. By rearranging the given linear equation, it is possible to isolate y on one side to express it in the slope-intercept form.
