Answer:y = 7x/4 and y = 2x/3 are proportional.
Explanation:
In a proportional relationship, for any value of one variable, the is a corresponding change in value of the other variable. This means that there is a constant variation between both variables.
Looking at the equations given,
Looking at the equations given,
y = 7x/4
If x = 1, y = 7×1/4 = 1.75
If x = 2, y = 7 × 2/4 = 3.5
If x = 3, y = 7 × 3/4 = 5.25
It is proportional because the constant of variation is 1.75
y = 2x/3
If x = 1, y = 2×1/3 = 0.67
If x = 2, y = 2 × 2/3 = 1.33
If x = 3, y = 2 × 3/3 = 2
If x = 4, y = 2 × 4/3 = 2.67
It is proportional because the constant of variation is 0.67
