If anyone knows this please tell me asap! due for tonite pls help <33 x

Step-by-step explanation:

At y intercept, x = 0. So, y-intercept = b = 9

Slope intercept form : y = mx + b

y = mx + 9

To find the slope, take any point on the line.(2 , 5)

Substitute x and y values in the above equation and now we can find the value of m

5 = m*2 + 9

5 - 9 = 2m

-4 = 2m

-4/2 = m

m = -2

Equation of the line:

y = -2x + 9

ratio is 2 : 9

the answer is three

13.5 : 3

they would have to work 32 hours.
