Answer:
A situation represents a proportional relationship if you can write equivalent ratios of related quantities in that situation.
Q
Answer:

Step-by-step explanation:
Point-slope form: y - y1 = m(x - x1)
Slope: 
Point: (3, 2) = (x1, y1)
To write the equation in point-slope form, we need to know the values of the slope and one point. Since we've already been given those values, all we have to do is input them into the equation:
y - y1 = m(x - x1)

The equation in point-slope form is: 
Answer:
-83, -85
Step-by-step explanation:
355 miles/17 gallons ≈ 20.88 miles per gallon
284 miles ÷20.88= 13.6 gallons needed
Answer:
x = 21.
Step-by-step explanation:
AS there are parallel lines:
4/12 = 7/x
4x = 84
x = 84/4 = 21.
