Question

What is the slope of (3,9) and (5,7)

Answer 1

Answer:

The slope is 1 and the y-intercept is 4.

Step-by-step explanation:

According to the rise-over-run formula:

y2 - y1

x2 - x1

We can insert 9 and 7 into the top (y) half

9 - 7

x2 - x1

and we can insert 5 and 3 to the bottom (x) half.

9 - 7

5 - 3

Continuing:

2 = 1

2    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.)
