Geometry question plz help me!

Answer:

Step-by-step explanation:

Any linear equation can be written as y = mx + b

The point will determine b

The slope (m) is found by this formula for a perpendicular line

m1 * m2 = - 1

m1 = -1/m2

m1 = -1/(-2/3)

m1 = 3/2

So our equation looks like

y = 3/2 x + b

Now we use the point (4,-8)

-8 = 3/2 (4) + b

-8 = 3(2) + b

-8 = 6 + b

b = - 14

The answer is

y = 4/2 - 14

Jackson wants to purchase a home theater system that sells for $2500. Either he can pay the total amount at the time of purchase
N76 [4]

Answer:

$90

Step-by-step explanation:

To find out how much money he can save by paying the total amount at the time of purchase, first you have to determine the total amount that Jackson would pay if he can agree to pay $250 down and $130 a month for 18 months:

$250+(130*18)=$2590

Then, you need to find the difference:

$2590-$2500=$90

According to this, the answer is that you will save $90 by paying the total amount at the time of purchase.
