Answer:
The slope is -2 and the slope-intercept form is y=-2x+20
Explanation:
To find the slope between two points, remember to use the equation y2-y1 over x2-x1. That will help you get the slope. To find the y-intercept, use any of the two points given and insert the slope into the equation y=mx+b. For this one I used the two points (7,6)
