Find the equation of the line passing through the points (7,20) and (-2,11)

y = x + 13

Step-by-step explanation:

Step 1: Find the slope

(11-20) / (-2-7) = 1

Step 2: Find b

y = x + b

20 = 7 + b

b = 13

Step 3: Put it all in slope-intercept form

y = x + 13

And you should have your final answer!

the coordinates of a' are (-5, 10)

what i did is i   turned 2 1/2 into an improper fraction which is 5/2. then i multiplied this (the scale factor) by the coordinates of a which is (-2,4).

hope this : )
