The solution is

solution

The first equation is

The

-intercept

is 0. Plot the point

(

)

The slope is 6. Move up 6 and right 1 to find another point on the line.

Draw a line connecting them.

The second equation is

–

The

-intercept

–

Plot the point

(

–

)

The slope is 8. Move up 8 and right 1 to find another point on the line.

Draw a line connecting them.

Finally, identify the point of intersection.

The lines intersect at
