Answer:
y = x/2 +4
Step-by-step explanation:
new slope = -1/-2 = 1/2
x1 = -4, y1= 2
y-y1 = m(x-x1)
y - 2 = 1/2 {x- (-4)}
y-2 = 1/2 (x+4)
y-2 = x/2 + 2
y = x/2 +2+2
y = x/2 +4

Find an order pair (x,y) that is solution to the equation 3x-y=8
Answers
Answer:
(2.67,-8)
Step-by-step explanation:
You first make x 0 so it is -3x0 to cancel that out to find y. You then see that you get -y=8 so you make y positive by moving the negative to the other side to get y = -8. Then, you do the same type of process for x and get 2.67. I could be wrong but wanted help as much as I could!

Mr. Bates and Ms. Psenicska like playing Pokemon. Mr. Bates has 3 packs of cards plus 2 other cards. Ms. Psenicska has 6 packs of cards plus 8 other cards. White an algebraic expression to represent this scenario.
Answers
Answer:
The only algebraic expressions we can find here are the ones for the number of cards that Mr. Bates and Ms. Psenicska have.
We know that Mr. Nates has 3 packs of cards, plus 2 other cards.
If each pack of cards has N cards, then the total number of cards of Mr. Nates is:
Mr. Nates = 3*N + 2
And Ms. Psenicska has 6 packs plus other 8 cards, then she has a total of:
Ms. Psenicska = 6*N + 8
These two are the only expressions we can make with the given information.

What is 2(5 to the second power) +3(5) - 12
Answers
Answer:
53
Step-by-step explanation:
Anya found the slope of the line that passes through the points (–7, 4) and (2, –3). Her work is shown below.
Let (x2, y2) be (–7, 4) and (x1, y1) be (2, –3).
m = m equals StartFraction x 2 minus x 1 over y 2 minus y 1.
= Equals StartFraction negative 7 minus 2 Over 4 minus negative 3.
= Negative StartFraction 9 Over 7 EndFraction.
The slope is Negative StartFraction 9 Over 7 EndFraction..
What error did she make?
She simplified the denominator incorrectly. The denominator simplifies to –7.
She labeled the points incorrectly. The point (–7, 4) should be (x1, y1).
She used an incorrect formula. The formula should be the change in y-values with respect to the change in the x-values.
