The compact will save 3 miles a gallon. The compact will have 12 miles on 24 miles a gallon while the minivan will have 9 miles on 18 miles per gallon.
y = 3 x equation represents a proportional relationship.
Answer: Option B
<u>Step-by-step explanation:</u>
A proportional variation represents a relationship between two variables x and y. It can be expressed in the form y=k x. Here, the ‘k’, the proportionality constant is equal to the slope m and the line goes through the origin
case A) 
A linear equation that not passes through the origin and so not proportional variation
case B) y= 3 x
Is a linear equation but passes through the origin and so proportional variation
case C) y = - 3x+2
A linear equation that not passes through the origin and so not proportional variation
case D) 
An inverse variation equation but not passes through the origin and so not proportional variation.
From these, equation option B is the proportion equation because in these equations, there is no addition and subtraction of any constant number. That’s why both these equations become proportional equations.
Line v passes through points (1, 12) and (10, 7). The slope of line w as improper fraction is 
<u>Solution:</u>
Given, two points are (1, 12) and (10, 7)
We have to find the slope of a line that is perpendicular to line passing through the above given two points.
Slope of a line that pass through
is given as:



So, slope of line v is 
Since<em> </em>line w is perpendicular to v,<em> the product of their slopes equals -1</em>



Hence, the slope of line w as improper fraction is
