Question

Which equation doesn’t belong with the others: y=4x, y=x + 7, y=-2x+4 & y=3x-1

Answer 1

The equation
`y = 4 \cdot x` does not belong to the set.

Explanation:

The set represent a group of linear equations in explicit form with non-zero coefficients. Hence, the equation
`y = 4 \cdot x` does not belong to the set.

Answer 2

y = -2x+4

Explanation:

The third linear equation doesn't belong with the others, beacuse it has a negative slope.

The common characteristic between functions is that all of them have a positive slope (coefficient of the independent variable) except for the third function, which has a negative slope.

Therefore, the right answer is C.
