200

In the equation y = 1/3 x - 5, which number represent the slope?

1/3

300

On your whiteboard, graph y = 7/8 x

Runds through origin and goes up 7, right 8...will have a positive slope and run upward from left to right

400

On your whiteboard, graph y = - 4/5 x +3

Will run through 3 on y-axis and go down 4, right 5 OR up 4, left 5

*Will run downward left to right

500
