Answer:
Step-by-step explanation:
1. You just plot the points
2. To plot the line you have to find the slope and y-intercept
Slope =
=
= 
Slope = 
Y-intercept = 
Y-intercept: y - 15 =
(x - 2)
y - 15 =
+ 15
Add 15 to both sides
y =
x + 30 this is the equation of the line.
So you start with the starting point and then the slope!
