How to find the slope

What is the formula to calculate the slope of a line?

• m = (rise in x) - (run in y)

• m = (rise in y) + (run in x)

• m = (change in x) / (change in y)

• m = (change in y) / (change in x)

How do you calculate the slope if you know two points on the line?

• Multiply the x-values difference by the y-values difference

• Add the x-values and divide by the y-values sum

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

• Subtract the y-values and divide by the x-values difference

Why is the slope of a vertical line considered undefined?

• Because it has a zero run

• Because it has a zero rise
