Determine which of the following graphs is the graph of 8x + 9y - 72.

Step-by-step explanation:

To figure out your x-intercepts and y-intercepts you have to redo the equation and make it equal to zero.

Step 1: 8x + 9y - 72 = 0

Step 2: 8x + 9y = 72

Now you can figure out your intercepts! As long as you use the STANDARD FORM EQUATION which is Ax + By = C

Y-INTERCEPT (vertical line): ( , 0 )

X-INTERCEPT (horizontal line): ( 0 , )

Insert your numbers how it shows in the standard form equation and you should get something like this:

Y-INTERCEPT: ( , 0 )

Simplified Y-INTERCEPT: ( 8 , 0 )

X-INTERCEPT:  ( 0 , )

Simplified X-INTERCEPT: ( 0 , 9 )

Insert that into your graph and you should be able to get your answer.
