Question

What is the graph of the system y = –2x + 3 and 2x + 4y = –8?

Answer 1

y = –2x + 3
slope = -2
y-intercept = (0,3)
x-intercept = (3/2,0)
With two points you can draw a line.
.
2x + 4y = –8

4y = -2x -8
y = -(2/4)x -8/4
y = -(1/2)x -2
slope = -1/2
y-intercept = (0,-2)
x-intercept = (-4,0)
