for problem 6, you will want to subtract both sides by 5.
n^2 + 7n + 10 = 0
then factor:
(n + 5) (n + 2) = 0
n+ 5 = 0, n +2 = 0
n = -5, n = -2
----------------------------
for problem 7, add - 12 and - 6 together
n^2 + 3n - 18
<em>(you can put </em>= 0 <em>next to the equation since that can make it easier to solve, I guess)</em>
n^2 + 3n - 18 = 0
then factor:
(n + 6) (n - 3) = 0
n + 6 = 0, n - 3 = 0
n = -6, n = 3
It would be 55.125 as a decimal, but as a fraction it would be 441/8.

QUESTION
Your equation is 2x+3y=2 and you need to find the slope.
EXPLANATION
There are many ways to find the slope with an equation like this. I'm going to change the equation into slope-intercept form.
Slope-intercept form is formatted like this:
y=mx+b
m represents the slope. The first thing you need to do is leave 3y alone to change the equation into slope-intercept form. That means you need to subtract 2x from both sides.

The next thing you need to do is leave y alone, just like the slope-intercept form example. To leave y alone, you need to divide 3y by 3.

Now the equation has been changed to slope-intercept form. In the equation, m has been replaced by
, which means that is your answer.
