Answer: change in y and change in x is 3
Step-by-step explanation:
Change in y/ change in x = slope
Slope = y2-y1/x2-x1
To find the slope (-1-2),(2,7), we first locate the coordinate points.
X1 = -1, X2 = 2
Y1 = -2, Y2 = 7
Insert the values into the formula:
Slope = 7 - (-2)/ 2 - (-1)
= 7 + 2/ 2 + 1
= 9/3
Slope = 3
