Answer:
y = 3x+2
Step-by-step explanation:
First we need to find the slope
m = (y2-y1)/(x2-x1)
= (23-20)/(7-6)
=3/1
We know the slope is 3
Using the slope intercept form of a line
y= mx+b where is the slope and b is the y intercept
y = 3x+b
Using a point (1,5)
5 = 3(1)+b
Subtract 3 from each side
5-3= 3-3+b
2 = b
y = 3x+2
