Answer:
Step-by-step explanation:
Equation of a line giving 2 points is
y-y1=m(x-x1) where m is the slope and (x1,y1) is one of the points.
First we have to find the slope using formula
(y2-y1)/(x2-x1) where (x1,y1) and (x2,y2) are the points given
Slope m is (4-13)/(8--4) =-9/12 = -3/4
Looking at the answer choices, the only slope intercept equation that use the slope -3/4 is answer choice A
Associative property of addition
Answer:
Step-by-step explanation:
-6y = -5x + 36
y = 5/6x - 6
Answer:
B.
Step-by-step explanation:
First you need to figure out how many numbers there are, so with this you can simply count 10. Then use the formula to plug in the numbers: 10(22-77)/2 to get the answer.
(the opposite of the multiplication of 6 is to divide each side by 6)
6y = 192
6y ÷ 6 = 192 ÷ 6
y = 192 ÷ 6
y = 32
The answer is D. 32
