# How do you find the slope and y intercept and graph - 4x + y =9?

##### 1 Answer

y = 4x + 9

slope = 4 or 4/1

rise 4 run 1

y intercept = 9

#### Explanation:

Begin by isolating the variable y.

-4x + y = 9

-4x + 4x + y = 4x + 9

y = 4x + 9

y = mx + b

m = slope m = 4

b = the y intercept b = 9

graph{y = 4x + 9 [-10, 10, -5, 5]}
