Slope-Intercept Form (help, please, ASAP!)...?

Question

Okay. I know how to do slope-intercept form (y=mx+b), but on our assignment it's giving a chart that looks like:

How does that chart fit into this? The only instructions are, "Graph each equation by plotting points".

All I need is for you to help me out with 2 problems, then I'm pretty sure I can figure out the rest of it.

1.) y = x + 2
2.)2x + 2y = 8

Yeah you're probably thinking, "Easy stuff!".... I just don't know how the chart plays into this. If someone could explain the chart or whatever, please do! {{assignment due tomorrow, so help is wanted right away!}}

And for the smart allecks, don't tell me, "You should've asked your teacher". I didn't realize the chart thingy was on the assignment.

Thanks!

Answer 1

The chart is a starting point for plotting the graphs. First put the equations into slope intercept form. Then solve for x using the values that are given for y in the chart. All you have to do is graph them after that. You don't have to use the cahrt, it is probably just a guideline so you get whole numbers...

Answer 2

The chart thingy will give you values to use in place of y. So if your chart has a y value of 2 replace y with 2 and solve for x in your equation. That will give you your ordered pair to graph. It looks like you are going to get 3 ordered pairs and then you get to play connect the dots.

Hope this explanation helps.

Answer 3

For the chart you plug in the x values, get y values and then plot it on your graph paper.

for example

y = x + 2
slope = 1
y int = 2

start plugging in the points
x = -2, y = 0
x = 2, y = 4
x = 3, y = 5

now go pencil those points in on your graph paper and trace out the line for the plot.

I think 1 example is enough you should be able to do this

Answer 4

i'm sure cause its a short time since i study about that let mee see:
y=x+2

finding x:
0=x+2
-x=2
-x/-1=2/-1
x=-2

finding y:
y=0+2
y=2

2x+2y=8

finding x:
2(0)+2y=8
2y=8
2y/2=8/2
y=4

finding y:
2x+2(0)=8
2x=8
2x/2=8/2
x=4
