# Math Help - Slope/Graph--Algebra ?'s

1. ## Slope/Graph--Algebra ?'s

I need help with 5.
I'd like problems 1,2,3,4,6,9,10 checked to make sure they are right.
And I need help with 7,8,9

Prob 5:

I got this for the slope, but I'm at a loss for how to graph the thing.

Also I did these and was wondering if anyone could check them.

(Though I must admit my confusion for this one)
-6-1
____
-9-6 = -7/-15 And I'm not sure whether I should write it as: -7/-15, -7/15, 7/15 ??

Am I really supposed to have a new thread for each problem? Seems a bit spamful >>

2. 5) The slope is correct and the graph is A
1) Correct
2) Correct
3) Correct
4) The slope is $\displaystyle\frac{7}{15}$
6) Correct
10) Correct
7) The equation is $\displaystyle y+4=\frac{7}{19}(x+2)\Rightarrow 7x-19y=62$
8) The slope is $\displaystyle\frac{5}{7}$.
The equation is $\displaystyle y+8=\frac{5}{7}(x-5)\Rightarrow y=\frac{5}{7}x-\frac{60}{7}$
9) B
