Answer:

Solving for X: x = 8

Step-by-step explanation:

Set up as proportion and cross multiply to solve:

12/15 = x/10

x = 8

y = x + 10

y = 8 + 10

y = 18

Slope Formula: $m= \frac{ y_{2} }{ x_{2} } - \frac{ y_{1} }{ x_{1} }$

I am going to show you how to do this on problem 6, and you will do the rest of the problems.

Here are the steps to solving problem 6

Step 1) Substitute the coordinates into the slope formula

$\frac{-1-2}{-18-(-8)}$

Step 2) Now Lets simplify the denominator, so we don't have two Subtractions symbols.

$\frac{-1-2}{-18+8}$

Step 3) Simplify

$\frac{-1-2}{-18+8} = \frac{-3}{-10}$

Step 4) We can still simplify more

$\frac{-3}{-10} = \frac{3}{10}$

Hope This Helps ... Good Luck

[The reason I didn't do all of them is because you need to know how to do them. Trust me later on knowing these is going to be very handy.]
