Answer:

1/ m = -3

2/ m = 3/2

3/ m = - 1/2

4/ m = 1/3

Explanation:

The slope is rise/run

1/ We see that the y decrease by 3 and the x go over by 1, so the slope is -3.

2/ We see that the y increase by 3 and the x go over by 2, so the slope is 3/2.

3/ Let's pick 2 points ( 0,5) ( 10,0), we see that the y decrease by 5 and the x go over by 10, so our slope is -5/10 = -1/2

4/ The equation of number 4 is in slope-intercept form, y=mx+b; we see that the equation is y= 1/3x - 3/2, so the slope is 1/3.
