Answer:
Slope is 20 and y-intercept is 40.
Step-by-step explanation:
First, let's find slope. I'll be using the points (1,60) and (3,100).
[tex]m=\frac{y2-y1}{x2-x1}=\frac{100-60}{3-1}=\frac{40}{2}=20[/tex]
So the slope is [tex]m=20[/tex]. Now we need to find y-intercept. We can do this by using our slope and a point in the point-slope equation, [tex]y=mx+b[/tex]. I'll use the point (1,60).
[tex]y=mx+b\\60=20(1)+b\\60=20+b\\b=40[/tex]
I hope this helps!
