Question

For each equation in the table, give the slope of the graph.

Answer 1

1. undefined

2. 0

3. -6

Explanation:

Slope-intercept form: y = mx + b

m = slope

b = y-intercept.

Since the equation x = -6 is a vertical line, the slope is undefined.

Since y = -6 is a horizontal line, the slope is 0.

The slope of y = -6x is -6. This is because it is the coefficient of the variable x.

Answer 2

x=-6 is undefined

y=-6 is 0 or m = 0

y=-6x is -6 or m = -6
