If the slope of a line is 3, then what is the value of n when (2, -8) and (n, 1) are on the line?

n = 5

Step-by-step explanation:

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 - (-8)) / (n - 2)

3 = ( 1 + 8 ) / ( n - 2)

3 = 9 / ( n - 2)

n - 2 = 9 / 3

n - 2 = 3

n = 3 + 2

n = 5

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.
