Answer:
y = x + 18
Step-by-step explanation:
slope:
m = (y₂ - y₁) / (x₂ - x₁)
= (10 - 18) / (-8 - 0)
= -8 / -8
= 1
y-intercept using m from above and anyone of given points, let's use (0, 18):
y = mx + b
(18) = 1(0) + b
b = 18
Using m and b from above form equation of line:
y = mx + b
y = 1x + 18 or y = x + 18
