**Jai**, Sunday, October 6, 2013 at 10:22pmIt's hard to show here the actual graph so I'll just tell you what to do. There are plenty of ways to graph them, but this is, for me, the simplest:

1. First, find the x- and y-intercepts.

To the x-intercept, let y = 0 and solve for x. To find the y-intercept, let x = 0 and solve for y.

2. Then plot the points on a Cartersian plane.

3. Draw a line connecting the two points, and you have the graph!

Let's take the first equation as example: y = 2x + 5.

For the x-intercept, (let y=0)

0 = 2x + 5

2x = -5

x = -5/2

Thus the point is (-5/2, 0)

For the y-intercept, (let x=0)

y = 2(0) + 5

y = 0 + 5

y = 5

Thus the point is (0, 5)

Then get a graphing paper and plot these points, and connect them with a line.

Hope this helps~ :3
