How do I solve the following by using graphing?

y=4x+9

10x=18 - 2y

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
