You can put this solution on YOUR website! y=9x-10
y=-4x+18
I dont know the first step to solving this!
I am supposed to solve by graphing
---------------------
Equation gives a graph of a straight line.
Find 2 points for each eqn, then draw a line thru them.
Where the lines cross is the solution of the system.
------------------------
y=9x-10
Pick 2 values for x and find y.
x = 0, y = -10 --> (0,-10) 1 point
x = 1, y = -1 -- (1,-1) a 2nd point
Plot those 2 points, draw a line thru them.
-----------------------
Do the same for the other eqn.
