Write the equation in slope-intercept form with the point (2,7.5) with an x intercept of −1.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.

Since we know that the line passes through the point (2,7.5) and (-1,0), we can find the slope with this formula:

Substituting values, we get:

In order to find the y-intercept, we can substitute the slope and the point (-1,0) into and then solve fo "b":

Then, the equation of this line in Slope-Intercept form is:
