Answer:
The slope is 1 and the y-intercept is 4.
Step-by-step explanation:
According to the rise-over-run formula:
<u>y2 - y1</u>
x2 - x1
We can insert 9 and 7 into the top (y) half
<u>9 - 7</u>
x2 - x1
and we can insert 5 and 3 to the bottom (x) half.
<u>9 - 7</u>
5 - 3
Continuing:
<u>2</u> = <u>1</u>
<u>2</u> 1
Slope = 1.
(Finding y-intercept you can insert (3, 9) or (5, 7) into y = mx+b, finding B and inserting your slope into m.)
