Answer:
[tex]y = \frac{x}{3} - 8[/tex]
Step-by-step explanation:
You use:
y-y1=m (x-x1)
First, find the gradient (m) using
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
[tex] \frac{ - 5 - - 7}{9 - 3} [/tex]
=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
