The line has a positive slope. Let's look at all the slopes:
1) -3
2) -3
3) 3
4)3
Which ones are positive? That's right, 3 and 4. We don't know which equation would be the equation of the line. That's where the other information comes in.
The line intersects the y-axis at at a point that has a negative y-coordinate. Lets write the last two equations in slope-intercept form.
1) y = -3/2x - 5/2
2) y = -3/2x + 5/2
We have to graph both of the lines now. The graphs are at the very bottom. Take a look at them. In the first one, the y-intercept is a negative and in the second one, the y-intercept is positive.
The third one AKA 3x + 2y = -5 is the equation of the line. I hope this helps! Let me know if I got it wrong or if you need any more help.

Answer:
heres an example of substitution in a world problem. hope this helps on some other problens
Both problems give you a function in the second column and the x-values. To find out the values of a through f, you need to plug in those x-values into the function and simplify!
You need to know three exponent rules to simplify these expressions:
1)
The
negative exponent rule says that when a
base has a negative exponent, flip the base onto the other side of the
fraction to make it into a positive exponent. For example,
.
2)
Raising a fraction to a power is the same as separately raising the numerator and denominator to that power. For example,
.
3) The
zero exponent rule<span> says that any number
raised to zero is 1. For example,
.
</span>
Back to the Problem:
Problem 1
The x-values are in the left column. The title of the right column tells you that the function is
. The x-values are:
<span>
1) x = 0</span>Plug this into
to find letter a:
<span>
2) x = 2</span>Plug this into
to find letter b:
<span>
3) x = 4</span>Plug this into
to find letter c:
<span>
Problem 2
</span>The x-values are in the left column. The title of the right column tells you that the function is
. The x-values are:
<span>
1) x = 0</span>Plug this into
to find letter d:
<span>
2) x = 2
</span>Plug this into
to find letter e:
<span>
3) x = 4
</span>Plug this into
to find letter f:
<span>

Answers: a = 1b = </span>
<span>
c = </span>
d = 1e = 
f =
