Answer:
y = -5x +7
Step-by-step explanation:
Answer:
8.5
Step-by-step explanation:
The length of a segment can be found from its end coordinates by using the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((8 -2)² +(4 -(-2))²) = √(6² +6²) = √72
d ≈ 8.485 ≈ 8.5
The length of MN is about 8.5 units.
Answer:

Step-by-step explanation:
Let x be the percentage then...

Start by dividing both sides by 4:

Simplify the fraction:

Then, multiply the fraction by 50/50, so we can get a number over 100 (that number would be the percentage). Note we can only multiply it by 50/50 since it is essentially multiplying the fraction by 1.

1. x = 3, y = 2
2. x = -99/68, y = -14/17
3. x = -4, y = 1
4. x = 1, y = 5
5. x = -1, y = 0
6. x = 2, y = -3
7. x = 14, y = 20
I attached the pictures with the work.
You can use the formula y1-y2=m(x1-x2)
to find m, you just do (y2-y1)/(x2-x1) so....
(115-80)/(80-40)= 35/40= 7/8
then plug it into the point slope equation:
y-115=7/8(x-80)
y-115=7/8x-70
y= 7/8 x + 45
