My answer is 35 because if you do 3 times 7 then 2 times 7 which equals 21 and 14 then add and you get 35. well that's my answer
Construct a triangle out of the points then find the midpoint of each side
Turn the equation into slope-intercept form.
-x + y = 4
y = 4 + x
y = x + 4
The slope of a perpendicular line is the opposite and reciprocal of the original.
x -> -x
Now, we need to find a y-intercept that crosses through the point (-1,8).
(0, 7) works
Therefore, the answer is y = -x + 7
Best of Luck!
