What is the slope of a line that contains points (3, 10) and (3, -2)?

To find the slope, using the coordinates, you will plug them into the slope formula.

Slope formula:

You plug in the 2nd Y-cordinate in y2 and the 1st y-coordinate in y one. Then you do the same thing for the-x coordinates. Plug in the 2nd x-cordinate in x2, and 1st x-cordinate in x1.

You plug in -2 and 10 in the y2 and y1, respectively. Also, you plug in 3 and 3 in x2 and x1 respectively.

The equation you're going to get after plugging in is:

Then you solve the equation. You subtract -2 to 10, it will be the same as -2 + -10, you would get -12. Then for the bottom, 3-3 will end up as 0

You will end up with:

The answer you will get is undefined after completing all of the steps with the slope formula. The reason why it's undefined is because with the fraction () you rise (up) over run (right). And the -12 would be your rise, and 0 would be your run. Since the run value is 0, you're only going to go up or down in a straight line. And you can't define what the slope is.

The slope of the line is undefined.

expression #3 is not equivalent. the others are.
