Answer:
Represents a direct variation
Explanation:
y = 2/7x
To find x-intercept/zero, substitute
y = 0
0 = 2/7x
Multiply both sides of the equation by 7/2
0 = x
Swap the sides of the equation
x = 0
Solution
x = 0
This is a direct variation because when x = 0. Y has to = 0 as well and it is so that makes this equation a direct variation.
direct variation - mathematical relationship between two variables that can be expressed by an equation in which one variable is equal to a constant times the other
