    To make it easy to graph, you probably want to change the second equation to y = mx + b form, like the first. Then graph by using the value of b as the y intercept (the value of y when x = 0) and m is the slope. Then the solution of the two equations is where the two lines meet.

    10x=18-2y

    -18. - 18

    10x-18=2y divide everything by 2

    5x-9=y

    M=5

    B=-9 (0,-9)

    To graph start at - 9 then go up 1 and then go to the right 5 times because it needs to be a positive line

    Y=4x+9

    M=4

    B=9 (0,9)

    Do the same thing as the other one
