Question

Write an equation that represents the line.
Use exact numbers.

Answer 1

y=-2x-3.

Explanation:

y=mx+b

First, find the slope:

points: (0,-3)(1,-5)

RISE OVER RUN: y2-y1 divided by x2-x1 = slope

-5--3=-2

1-0= 1

-2/1 = -2

SLOPE = -2

For the y-intercept (b) we look at where x=0, whatever value y is when x=0, is our y-intercept. In this case, our y-intercept is -3.

Therefore, y=-2x-3
