Answer:
y = 2x+10
Step-by-step explanation:
We have 2 points we can find the slope
m = (y2-y1)/(x2-x1)
= (12-4)/(1--3)
= 8/(1+3)
= 8/4
=2
The slope is 2
We can use the point slope form of the equation
y-y1 = m(x-x1)
y-4 = 2(x--3)
y-4 = 2(x+3)
Distribute the 2
y-4 = 2x +6
Add 4 to each side
y-4+4 = 2x+6+4
y =2x+10
Now this is in the form y= mx+b
