Question

Which graph represents a linear function?

On a coordinate plane, a parabola opens down.
On a coordinate plane, a line has a negative slope.
On a coordinate plane, a line curves up.
On a coordinate plane, a line curves down, levels off, and then curves down.

Answer 1

Answer : on a coordinate plane, a line has a negative slope. the second one

Answer 2

On a coordinate plane, a line has a negative slope

Explanation:

A linear function is a function whose graph is a straight line. For example, y = 3x - 2 represents a straight line on a coordinate plane and hence it represents a linear function.
