Write a linear equation that passes through the points (-3,3) and (9,-13) !

Step-by-step explanation:

y = mx + b

m = delta y / delta x

m = (-13 - 3) / [(9 - (-3)]

m = -16/12

m = -4/3

From (-3 | 3) we know that when x = -3, y = 3

Placing into equation to find b

3 = (-4/3)*-3 + b

3 = 12/3 + b  

b = -1

step-by-step explanation:

b

step-by-step explanation:

calculate the scale factor as the ratio of corresponding sides, image to original, that is

scale factor = = = = 1
