Answer:

Note: m means slope

1. m = 3

2. m = -4/6

3. m = 2/4

4. m = 0

Step-by-step explanation:

Note: slope-intercept form is y = mx + b

1. y-intercept is (0, -9) and x-intercept is (3, 0)

m = rise/run or m = (y2 - y1)/(x2 - x1)

using our points (0, -9) and (3, 0)

we can substitute the values and solve for slope:

m = (0 - (-9)/(3 - 0) = 9/3 = 3

m = 3

2. (0, 4) y-intercept (6, 0) x-intercept

m = (y2 - y1)/(x2 - x1)

m = 0 - 4/6 - 0

m = -4/6

3. (0, -2) y-intercept (4, 0) x-intercept

m = (y2- y1)/(x2 - x1)

m = 0 - (-2)/4 - 0

m = 2/4

4. we have an y-intercept of (0,3) i think but it doesn't matter because looking at the graph there is no slope because we do not have any change in the y value.
