To make the equation easier to look at change it to this:
y = 15 - 3x
To find the x intercept say y = 0.
0 = 15 - 3x
Subtract 15 from each side.
-15 = -3x
Divide each side by -3.
5 = x <–––– x-intercept
The y-intercept of the equation is 15.
Hope this helps!
Answer:
Harry is 2, Jim is 6
Step-by-step explanation:
The first statement tells us they are 4 years part. Then you need to find two numbers that are 4 apart and that has one that is half the other, like 4 and 8. Finally, subtract two because this will happen in two years and you need their ages now.
Sorry if this was confusing.

"Definition of direct variation. 1 : mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other."
The answer is D
All of the other relationships are consistent.
A is x × 3
B is x × 4
C is x × 2
D is x × 2 then 3 then 4.
D is not a direct variation.
