Answer:
c
Step-by-step explanation:
Translate that into an equation, and we get:
a+b = 24
a-b = 15
If we add these two equations, we get:
2a = 39
a = 39/2 = 19.5
Plug back in a = 19.5 and solve for b
a + b = 24
19.5 + b = 24
b = 4.5
The two numbers are 19.5 and 4.5.
Check the picture below.
so let's use those two points the line passes through to get its slope.
