Question

What is the slope-intercept form equation of the line that passes through (1, 3) and (3, 7)?

Answer 1

first find the slope of the line
If the 2 points are (x1,y1) and (x2,y2) the slope is

(y2-y1) / (x2-x1)

here x1 = 1 , x2 = 3 , y1 = 3, y2 = 7

Answer 2

so plug these into the formula and you can work out the slope

can you do that?

Answer 3

(7-3) / (3-1)

Answer 4

4/2

Answer 5

That's correct :) now you want to simplify 4/2

Answer 6

2

Answer 7

Answer 8

I know Y=mx+b

Answer 9

yes! :) So your slope (m) = 2

Now, since we know m = 2, we need to write an equation in slope-intercept form:
