How do you write the equation of a line in slope-intercept form when given two points on the line? the two points are (3,-7) and (9,-5)

Step-by-step explanation:

You use:

y-y1=m (x-x1)

First, find the gradient (m) using

=2/6

=1/3

Now choose either one of the points to substitute into the point gradient formula. Let's choose (3,-7)

y--7=1/3 (x-3)

y+7=1/3 (x-3)

Rearrange to get y=mx +b

y+7=(x/3)-1

y=(x/3)-8

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
