(r, 3), (5, 9), m = 2 find the value of r so the line that passes through each pair of points has the given slope and show

r = 2

Step-by-step explanation:

use slope formula to find r

(r, 3) (5, 9)  m = 2

y₂ - y₁ / x₂ - x₁ = m (Formula)

9 - 3 / 5 - r = 2 (use the points given then subtract 9 - 3)

6 / (5 - r) = 2 / 1 [Cross Multiply--2( 5- r ) = 6 x 1 ]

10 - 2r = 6 (solve equation)

-2r = -4

r = 2
