determine the x and y intercept, then plot the intercepts and graph thr line.
-36x-4y=36
9x + y = -9
--------------
x = 0 at the y-intercept and v.v.
x: (-1,0)
y: (0,-9)
------------
Draw a line thru the points.

x-intercept


To find the x-intercept, plug in y=0 and solve for x


-36x-4y=36 Start with the given equation.


-36x-4%280%29=36 Plug in y=0.


-36x-0=36 Multiply -4 and 0 to get 0.


-36x=36 Simplify.


x=%2836%29%2F%28-36%29 Divide both sides by -36 to isolate x.


x=-1 Reduce.


So the x-intercept is .

y-intercept


To find the y-intercept, plug in x=0 and solve for y


-36x-4y=36 Start with the given equation.


-36%280%29-4y=36 Plug in x=0.


-0-4y=36 Multiply -36 and 0 to get 0.


-4y=36 Simplify.


y=%2836%29%2F%28-4%29 Divide both sides by -4 to isolate y.


y=-9 Reduce.


So the y-intercept is .


Now plot the points (-1,0) and (0,-9)





Now draw a straight line through the two points to graph -36x-4y=36




Graph of -36x-4y=36 through the points (-1,0) and (0,-9)
