Answer:
Step-by-step explanation:
Answer:
the correct answer would be 13.5
Yes, these both are direct relationships and can be written like

, where k is the constant of variation.
For the first equation, k = 10. For the second equation, k = -4/3. You find it by rearranging the equation into the form

, and you use the coefficient of x for k.
Answer:
-2
Step-by-step explanation:
Isolate the variable y. Note the equal sign, what you do to one side, you do to the other. Divide 3 from both sides:
(3y)/3 = (15 - 6x)/3
y = (15 - 6x)/3
y = 5 - 2x
Note the equation:
y = mx + b
m = slope
b = y-intercept
x & y = the point (x , y)
Note that the slope is directly next to x. -2 is your answer.
