Answer:
 y=3
Step-by-step explanation:
The y values are the same, so there cannot be a slope. The (mx) part of y=mx+b is cancelled out, and is left with the b. Since the y value is forever three, the y-intercept will be 3 as well.
Therefore, the slope-intercept equation is 
y=3

Answer:
80
Step-by-step explanation:
We have, 75% × x = 60
or, 
75/ 100 × x = 60
Multiplying both sides by 100 and dividing both sides by 75,
we have x = 60 × 100/75
x = 80
