Step-by-step explanation:
m1.m2 = -1
18.m2 = -1
m2 = -1/18
formula = y - y1 = m2 ( x - x1)
y - (-5) = -1/18 ( x -1)
y + 5= -1x/18 +1/18
y = -1x/18 -89/18
The first one I think not sure
So first you do 3,816 divided by 12 , because you need to find how much for 1 so then you can find out 25% off of 1. To check your work put down 318 times 12 to prove that you're right. Which would be 318 times 25 = 79.5. If you use a calculator it won't have the decimals ( if you just do the numbers ), but the rest is above.
