What is the slope of the line that passes through the points (-10,4) and (-10,8)

UNDEFINED

Step-by-step explanation:

m = -y₁ + y₂\-x₁ + x₂ → -4 + 8\-10 + 10

40

Obviously, if we see two identical x-coordinates, the rate of change [slope] is AUTOMATICALLY an undefined slope, and also because we can NEVER divide by zero.

I am joyous to assist you anytime.

after going and makeing graphs i would go with a,

there is nothing that is matches the graph. if there was i would show you. but therefore my answer is a.

hope i
