(-2,5)(9,-6)
slope(m) = (-6-5) / (9 - (-2) = -11/11 = -1
y = mx + b
slope(m) = -1
(-2,5)...x = -2 and y = 5
now we sub and solve for b, the y int
5 = -1(-2) + b
5 = 2 + b
5 - 2 = b
3 = b
so ur equation in slope intercept form is : y = -x + 3
Answer:A = b x h

I can't see the problem but i can give help u have to follow the formuls
Answer:
C
Step-by-step explanation:
because density equal all the rest
Use a/ 1-r
Where a = 18 and r = 1.2
18/ 1 - 1.2 = 18/-.2 = -90
Because the answer is below 1. The sum does not exist therefore it diverges.
It takes Jack 2 1/4 hours (or 9/4 hours) to complete a project. John takes 3/8 hours longer.
We need to add 9/4 + 3/8
First, make the denominators equivalent.
We can do this by multiplying 2/2 to 7/2 which makes the denominator 8 (since 3/8 is already 8)
9/4 x 2/2 = 28/8
(note that we can do this because 2/2 is 1 and multiplying a number by 1 doesn't change its value)
Add 28/8 + 3/8
28/8 + 3/8 = 31/8
31/8 hours is our final answer, as a mixed number it is 3 7/8 hours :)
