What is the slope-intercept equation of y-intercept = (0, - 1) slope = - 2

Y = - 2x - 1

Step-by-step explanation:

Substitute - 2 for m, which is slope, and - 1 for b, which is y intercept

y = - 2x-1

Step-by-step explanation:

Slope intercept form is written as:

y=mx+b

where m is the slope and b is the y intercept

In this case, the slope is - 2 and the y intercept is (0, - 1). For this form, we ignore the 0 in (0,-1), and say the y-intercept is - 1.

So, m is - 2 and b is - 1. Substitute these values into the equation.

y=mx+b

m = - 2

b = - 1

y=-2x+-1

y = - 2x-1
