Understanding Slope from Two Points

What is the formula used to calculate the slope between two points?

• M = X2 - X1 over Y2 - Y1

• M = X1 - X2 over Y1 - Y2

• M = Y1 - Y2 over X1 - X2

• M = Y2 - Y1 over X2 - X1

In the example with points (0, 6) and (10, -2), what is the calculated slope?

• -4/5

• 4/5

• -5/4

• 5/4

When calculating the slope between points (3, -3) and (3, 22), what is the result?

• Undefined

• 0

• 5

• 1

In the example with decimal points (3, 7.5) and (9, 8.5), what is the slope?

• 1/6

• 5/1

• 6/1

• 1/5

Does the order of labeling X1, Y1, X2, Y2 affect the slope calculation?

• Yes, it changes the result

• No, it does not affect the result

• Yes, but only for decimal points

• No, but it affects the sign
