x – 2y = -2

x – 4y = 10 => x = 10 + 4y

_________

10 + 4y - 2y = -2

2y = -12

y = -12/2

y = -6 => x = 10 + 4y = 10 + 4*(-6) = 10 - 24 = -14

Only thing I need to know is what to do for the x on y = x + 3 and y = x
Ronch [10]

Answer:

Think of y = mx + b,

With y = x + 3, m = 1 so the slope is one, and b = 3 which is the y-intercept, so plot the point (0,3) on the y-axis.

To find the next point to plot go up 1 and over to the right 1 because slope is rise over run.

With y = x, the slope is still 1, but there is no y-intercept, so you plot the point (0,0), and to find the next point on that line, go up 1 and over the right 1 because m=1
