Solve for r given the points ( 12 , 10 ) and (-2, r) and the slope, m = -4.

r = 66

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to - 4

m =

with (x₁, y₁ ) = (12, 10) and (x₂, y₂ ) = (- 2, r)

m = = , then

= - 4 ( multiply both sides by - 14 )

r - 10 = 56 ( add 10 to both sides )

r = 66

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
