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:
Feel free to copy and paste:
Use the slope-intercept form to find the slope and y-intercept. To do this, use y=mx+b. Plug the variables where m=1 and b=2. Slope of the line is m and y-intercept is value of b, so the slope is 1 while the y-intercept is (0,2). Any line can be graphed using two points, and using two x values to plug them into the equation to find the corresponding y values: 0=x+2 is (-2,0). Y-intercept is already known, so use the known values and make a table where x= -2,0 and y = 0,2. Now, graph the line using the slope, y-intercept, and known points (-2,0), (0,-2) to plot the graph. Coincidingly, the answer to solve your system of equations will be the x-intercept: (-2,0).
Answer:
it is 438
Step-by-step explanation:
(3x2 + 7y) (2x2 – 3x + 9)
=(6+7y)(-3x+13)
=-18x+78-21xy+91y
