Question

solve by graphing. x + 2y+4 and 4y - 2x = 24

Answer 1

graph the intercepts then extend to make the lines

Answer 2

get the equations into y=mx+b form to help

Answer 3

x + 2y = 4
-2x + 4y = 24 multiply the first equation by 2
----------------

2x + 4y = 8
-2x + 4y = 24 add them together, (the x terms cancel out)
--------------
0x + 8y = 32

8y=32

y=4 If y=4, put that into one of the equations, and solve for x=??

Answer 4

The point (x,4) will be the solution, and the intersection of the two lines.

Answer 5

To graph, let x=0, solve for y to get point (0,y)
let y=0, solve for x to get point (x,0)

Those are 2 points on the line, connect them, do that for both lines.
