Question

What is the slope of the line that

passes through these two points?
(-4, 6)
(-4,-2)

Answer 1

slope = undefined

Explanation:

To find the slope of a line that passes between two points, use the slope formula,
`m = (y_2-y_1)/(x_2-x_1)`. Substitute the x and y values of (-4, 6) and (-4,-2) into the formula and simplify like so:

`m = ((-2)-(6))/((-4)-(-4))\\m= (-2-6)/(-4+4) \\m = (-8)/(0)`

However, we can't divide by zero. This must mean that the slope of this line is undefined.
