FOLLOW - PEMDAS
Another way:
(4 • 3.2d) - (4 • 10)
(12.8d) - (40)
12.8d - 40
Answer:
Graph C
Step-by-step explanation:
y = .7x
For a direct variation, we know that the line has to go through the origin (0,0)
This eliminates graphs b and d. We also know that the slope is .7
When x = 1, y = .7. This eliminates graph a, because when x=1 y =1. This leaves us graph c
