(y - yo) = m.(x - xo)
(-2 - 2) = m.(2 - 10)
-4 = m.(-8)
m = -4/-8
m = 1/2
(y - yo) = 1/2.(x - xo)
(y - 2) = 1/2.(x - 10)
y - 2 = 1/2x - 5
y = 1/2x - 5 + 2
y = 1/2x - 3
Answer:
y = x - 3
Step-by-step explanation:
Slope formula:
Plug in the 2 points:
Plug either point and the slope into y = mx + b:
2 = (10) + b
solve for b:
2 = 5 + b
b = -3
Rewrite the equation:
