8x-6y=24 , 12x-9y=36 solve with graph

Answer»

To FIND the x-INTERCEPT, SET y=0 and solve for x.

8x-6y=24

8x-6%280%29=24

8x=24

x=3

(3,0)

To find the y-intercept, set x=0 and solve for y.

8x-6y=24

8%280%29-6y=24

-6y=24

y=-4

(0,-4)

The graph for 12x-9y=36 is GIVEN below.

\begin{gathered}12x-9y=36\\\frac{12x}{36}+\frac{9y}{-36}=1\\\frac{x}{3}+\frac{y}{-4}=1\end{gathered}

So x intercept is 3 and y intercept is -4.
