Question

Draw a graph of the line that goes through the points (-4, 7) and (0, 3)

What is the y-intercept and slope of the line you've drawn?

Answer 1

y = -x + 3

Explanation:

Use this formula to get the slope
`(y2 - y1)/(x2 - x1)`

PLUG IN

`(3 - 7)/(0 - -4) \\\\(-4)/(4) \\`

-4/4 = -1

The slope is -1

To find the y- intercept plug your slope and one of your points in this y=mx+b

We will use (0,3)

3 = -1(0) + b (b represents y-intercept)

3 = b

The equation would look like this

y = -x + 3

Hope this helps ya!!
