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 )
<em>Simplified Y-INTERCEPT: </em>( 8 , 0 )
X-INTERCEPT: ( 0 , )
<em>Simplified X-INTERCEPT: </em><em> ( 0 , 9 )</em>

Insert that into your graph and you should be able to get your answer.
Answer:
x =
Step-by-step explanation:
Given
2x + 5 = 12 ( subtract 5 from both sides )
2x = 7 ( divide both sides by 2 )
x = [ or x = 3.5 ]
