How do you calculate the slope if you are given two points?

• Multiply the x-coordinates and divide by the product of the y-coordinates

• Add the x-coordinates and divide by the sum of the y-coordinates

• Divide the sum of the x-coordinates by the difference of the y-coordinates

• Subtract the y-coordinates and divide by the difference of the x-coordinates
