Answer:
C
Step-by-step explanation:
We know it's direct variation using the direct variation equation.
Where k is the constant.
Since 7 times x is the y values,
Now we can substitute 7 into k of the direct variation equation.
j=2
Step-by-step explanation:
take the second numbers in each parentheses and subtract them. put this answer on top of a fraction
(j,3) (8,2)
2-3 = -1
take the first numbers and subtract. put this answer at the bottom of fraction
8 - J = 6
j = 2
answer should equal -1/6
the formula for a slope is y2-y1/x2-x1
look at the points like this, and fill in the places with the numbers and j they give you
(X1,y1) (X2,y2)
Answer:
9
Step-by-step explanation:
Solving the equation on the left we get
(x-9)^2
Answer:
C.
