Answer:
See the graph below
Step-by-step explanation:
Given the equation a = 15 + b
Before graphing, we need to get the a and b intercept of the equation;
a intercept occurs at b = 0
a = 15 + 0
a = 15
The a intercept is (15, 0)
The b intercept occurs at a = 0
0 = 15 + b
b = 0-15
b = -15
The b intercept is (0, -15)
Graphing the coordinates (15, 0) and (0, -15) as shown below
