I know ir but i just forgot cause i havent did it in a long time
for 2 points A(xa;ya) and B(xb;yb)
the slope is (yb - ya) / (xb - xa)
here
the slope = 4 = (17-r) / (4-(-1))
(17-r) / 5 = 4
17 - r = 20
r = 17 - 20
r = - 3
point (-1 ; -3)

Step-by-step explanation:
Answer:
Length: 9
Width: 2
Step-by-step explanation:
Area = length × width
18 = (x - 5)(x + 2)
18 = x² - 5x + 2x - 10
x² - 3x - 28 = 0
x² - 7x + 4x - 28 = 0
x(x - 7) + 4(x - 7) = 0
(x - 7)(x + 4) = 0
x = 7, -4(not possible)
Length: 7+2 = 9
Width: 7-5 = 2
