The two equations represent the proportional relationship.
y=3x and y=12x are proportional relation ship equations
proportion equations can be defined as
If we change x the y will change in the same proportion.
<h3>What is the proportional relationship?</h3>
Proportional relationships are relationships between two variables where their ratios are equivalent.
Another way to think about them is that, in a proportional relationship, one variable is always a constant value time the other.
That constant is known as the constant of proportionality.
proportional relationship equation contain (0,0) points
If we put x=0
This will give us,y=0
If we put x=0, in y=12x
It will give y=0
put if we put x=0 in
y=3x it will give us y=0
hence these two equations represent the proportional relationship.

Answer:
f(x)= 7.5x + 3
Step-by-step explanation:
you have 3 dollars just there, and you get 7.50 per car wash, so that is the x
Answer: slope: -1/4. Y-intercept: 9/8.
Step-by-step explanation:
Use the slope-intercept form y = mx + b to find the slope m and y-intercept b
<u>Answer</u>:
Linear equation.
<u>Explanation</u>:
It is linear as y increases 11 grids with every increase in x grid.
OR,
I will make a linear equation from two coordinates: (1,11),(2,22)
slope: 
→ 
→ 
the find equation using:
y - y1 = m(x - x1) → y - 11 = 11(x-1) → y = 11x ....this is linear equation.
Therefore it's linear.
OR,
Then check if 3rd and 4th coordinate matches the equation.
y = 11x y = 11x
y = 11(3) y = 11(4)
y = 33 ...therefore matches y = 44...therefore matches
So, its a linear equation.
