Question

which of the following equations is a direct variation equation that has the ordered pairs 12.5, 5 as a solutiona. y=7.5xb. y=x-7.5c. x=y+7.5d. y=2.5x e. y= -2.5x f. (2/5)x

Answer 1

The ordered pair given is 12.5, 5

This means that

When x = 12.5, y = 5

Looking at the given equations, if we substitute the values of x and y, the correct option would be C

The equation is expressed as

x = y + 7.5

By substituting, it becomes

12.5 = 5 + 7.5

12.5 = 12.5

The correct option is C
