Question

Identify the graphs that represent a linear function. Check all that apply.On a coordinate plane, a line has a positive slope.On a coordinate plane, a curve opens down.On a coordinate plane, a graph decreases, increases, and then decreases again.On a coordinate plane, a line has a negative slope.

Answer 1

A linear function is represented by a straight line, that means the right answers are those graph with straight lines.

Therefore, the right graphs are the first and the last one.

• The first graph represents a linear function with a positive slope.

,

• The last graph represents a linear function with a negative slope.
