Question

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

Answer 1

y= -2x-1

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

Answer 2

Y= -2x - 1

Explanation:

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