The graph that shows the proportional relationship y = 0.7x is Graph A.
<h3>What is a proportional relationship?</h3>
A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
In this problem, 7 out of 10 customers preferred the restaurants new spaghetti sauce, hence the constant is given by:
k = 7/10 = 0.7.
And the equation is:
y = 0.7x.
When x = 0, y = 0, which already eliminates graphs C and D. When x = 10, y = 7, which means that Graph A is the answer to this question.

The point (a,b) would be in quadrant 2 (the one on the top left)
A continuous data set is where you can plot every point (even very, very small decimal numbers) because the unit can be measured in parts of the whole.
A discrete data set is where you can only plot the units in whole values. For example, if you were plotting the number of people, you can't have a part of a person.
Weight is measured in lbs which can be measured in parts of the lb (such as 100.005 lbs) so it is continuous.
Answer: Continuous data set
I think it is the 3 one from the left side
Answer:
C = 1.5W
Step-by-step explanation:
Weight: W
Cost: C
C = kW
15 = k(10)
k = 1.5
C = 1.5W
