Answer 1

I don't know at all

Answer 3

You have a y-int of 1 and a slope of 1.
Change each equation into y=mx+b
m=slope
b=y-intercept

Answer 4

that suck me even more I suck at math @AlwaystheBookworm

Answer 5

the first suck was suppose to be made

Answer 6

Okay. Let's go through this step by step.
First, look at the graph.
You'll see that the line crosses the y-axis at 1. That is your y-intercept.
Now look at where the line crosses the x-axis at -1.
Looking at the two intercepts, you can see that it has a slope of 1.
The slope is rise/run.
Now you know the equation is y=x+1.
Look at your answer choices.
Take each one and convert it into the form of y=mx+b.

Answer 7

It you look at the first one, you have x-y=-1.
Bring the x to the other side.
-y=-x-1
You can not have a -y, so divide everything by -1.
y=x+1

Answer 8

If AlwaystheBookworm's approach (which I prefer) is not intuitive for you, you can always resort to the following formulas:

If we have two points on the line, (x1, y1) and (x2, y2), then we can determine the slope, m:

m = (change in y) / (change in x) = (y2 - y1) / (x2 - x1)

If we have the slope and we have a point (x1, y1) on the line, then a formula for the line is:

y - y1 = m * (x - x1)

Looking at the graph, one point is (0, 0) and another point is (1, 1).
