Answer:

Option D is your answer.

Step-by-step explanation:

Remember that the x-values are the x coordinates and the y-values are the y coordinates in an ordered pair. Ordered pairs are written like this (x,y).

So for line r, you got (-6,4), (-3,0), and (0,-4).

But you only need two of these pairs to determine slope. Let's do that real quick, by using this formula. (Sorry if it's small)⤵⤵⤵

\frac{y _{2} - y _{1} }{x _{2} - x _{1} }

We'll use (-6,4) and ( -3,0).

0 - 4 = -4

-3 - (-6) = -3 + 6 = 3

So slope of line r is -4/3.

Now we'll do the same for line s:

Ordered pairs = (-5,-4), (5,0), and (20,6)

We'll use (-5,-4) and (5,0).

0 - (-4) = 0 + 4 = 4

5 - (-5) = 10

So slope of line s is 4/10 or 2/5.

Now we got to find the option choice that has these as the slopes.

We'll turn each into slope-intercept form.

A)

- Subtract 4x on both sides to get

3y = -4x - 12, then divide 3 on both sides to get <u>y = -4/3 x - 4</u>.

- Subtract 2x on both sides to get

-5y = -2x + 10, then divide -5 on both sides to get <u>y = 2/5 x - 2</u>.

B)

- Add 4x on both sides to get

3y = 4x + 12, the divide 3 on both sides to get <u>y = 4/3 x + 4</u>.

- Subtract 2x on both sides to get

-5y = -2x - 10, divide -5 on both sides to get <u>y = 2/5 x + 2</u>.

C)

- Subtract 4x on both sides to get

-3y = -4x - 12, then divide -3 on both sides to get <u>y = 4/3 x + 4</u>.

- Add 2x on both sides to get

-5y = 2x + 10, then divide -5 on both sides to get <u>y = -2/5 x -2</u>.

D)

- Add 4x on both sides to get

-3y = 4x - 12, then divide -3 on both sides to get <u>y = </u><u>-</u><u>4/3 x + </u>4.

- Add 2x on both sides to get

5y = 2x + 10, then divide 5 on both sides to get <u>y = 2/5 x + 2</u>.

After all that writing we can tell that D is our answer, because both -4/3 and 2/5 appear as slopes.

Sorry this may seem like a lot, but the process really isn't that hard. Hope this helps :)
