4 0

4x - 5y + 20 = 0
 - 20 - 20
 4x - 5y = -20
4x - 4x - 5y = -20 - 4x
 -5y = -20 - 4x
 -5y = -4x - 20
 -5 -5
 y = ⁴/₅x + 4
The slope would be ⁴/₅.

Answer:

Step-by-step explanation:

8p+3f=10.39

5p+4f=10.51

subtract

3p-f=-0.12

f=3p+0.12

8p+3(3p+0.12)=10.39

17p=10.39-0.36

17p=10.03

p=10.03/17=0.59

f=3×0.59+0.12=1.77+0.12=1.89 $

or 40 p+15f-40p-32f=51.95-84.08

-17f=-32.13

f=1.89 $
