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

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

1/2 mile

Step-by-step explanation:

If you add 1/4 and 1 3/4, you get 2. Then, subtract 2 1/2-2=1/2
