Help me plzzzzzzzz!!!!!!

I need help with math.I dont know what to do here"Graph each line equaton" the problems are 1.y=x-1 2.y=3x 3.y=5+x 4.y=x+4 5.y=-5x 6.y=2-x 7.y=4-x 8.y=1 third (times)X... plzzz help me i really need help.

All you need are two points from each equation. For instance,

y = x - 1

Substitute 0 for x, then 0 for y. You get

y = 0 - 1
y = -1

0 = x - 1
1 = x

So your two points are (0, -1) and (1,0). Plot them on a graph and draw a line across them.

That technique is called finding the x and y intercepts. That's because those points are where the line intercepts the x and y axis. If x=0, then you're at the y axis. If y = 0, then you're at the x axis.

The next one can't use zeros, because you'll get (0,0) for both points, so use something like a 3.

y = 3(3)
y = 9

3 = 3x
1 = x

So you have the points (3,9) and (1, 3).

Just substitute something for x, then substitute something for y, and you'll get two points.

y = 5 + (0)
y = 5

(0) = 5 + x
-5 = x

You have (0, 5) and (-5, 0)

y = (0) + 4
y = 4

(0) = x + 4
-4 = x

You have (0, 4) and (-4, 0)

y = 5(5) (substituting 5 this time for each, because multiplying by 0 will always give you 0)
y = 25

(5) = 5x
1 = x

You have (5, 25) and (1, 5)

Get the picture?
