Question

Consider the following y-intercept and slope:

(0, -4), m = 4
Step 1 of 2: Find the equation of the line for the y-intercept and slope given above.

Answer 1

y = 4x - 4

Explanation:

The slope-intercept form pf an equation of a line:

`y=mx+b`

m - slope

b - y-intercept → (0, b)

We have the slope m = 4, and the point (0, -4) → b = -4.

Substitute:

`y=4x-4`

Answer 2

Answer:
`y=4x-4`

Explanation:

The slope intercept form of a line is given by :-

`y=mx+c` , where m is the slope of the line and c is the y-intercept.

Given : Y-intercept =(0, -4)

i.e. c= -4

Slope : m= 4

Then, the equation of the line for the y-intercept and slope given above will be :-

`y=4x+(-4)\\\\\Rightarrow\ y=4x-4`

Required equation :
`y=4x-4`
