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

Answer:

y = -3x -5

Step-by-step 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
