Question

Find the equation of the line in standard form that passes through the following points. Eliminate any fractions and simplify your answer.

(-8,0) and (-11,9)

Answer 1

First find the slope.
(9-0)/(-11 - -8) = 9/-3 = -3

Then find the y- intercept
y=mx+b
9=(-3)(-11) + b
9=33+b
-24 = b

y = -3x - 24

Now put in standard form

3x + y = -24
