Question

What is the equation of a line that goes through the point (0, -5) and has a slope of -3?

O y=-3x - 5
O -5y = - 3x
Oy = 3x - 5
O y = -5x-3

Answer 1

y = -3x -5

Explanation:

An order pair has an x and a y value (x,y) They give us a point on the line (0 -5) We will use this x = 0 and y = -5 and the slope -3 to write the equation

y = mx + b We need to find b. We will substitute everything else in.

-5 = -3(0) + b

-5 = b

y = -3x -5
