Question

Select the linear equation represented in the graph.

Answer 1

To find the linear equation, use the slope formula y = mx+b, where b is the value of the y-intercept and m is rise/run.

The line rises 1 unit and runs (left to right) -5 units. (you could also say the line runs -1 units and runs 5 units, they will both give the same answer). Rise/run, 1/-5 = -1/5.

The y-intercept is the y value where the line touches the y-axis. In this case, it is +1.

Plug the information into the equation. m = -1/5 and y = 1. y = -1/5x + 1
