Set Up Slope Formula

A line passes through the ordered pairs (0, 1) and (2, 6). What is its slope?

• m = -2/5

• m = 2/5

• m = 5/2

• m = -5/2

A line passes through the ordered pairs (4, 1) and (2, 8). What is its slope?

• m = -2/7

• m = 2/7

• m = 7/2

• m = -7/2

What did Ernie do wrong?

• He put x's on top and y's on bottom (he did run over rise)

• He changed the order of the points.

• He added instead of subtracting.

• He put one point in the numerator and one point in the denominator.

What did they do wrong?

• They added but they should have subtracted

• They changed the order of the points

• They did run over rise (x's on top, y's on bottom)

• They put one coordinate in numerator and one in denominator

• Yes, her work is set up correctly.

• No, the order she subtracted the y-values is different than the order she subtracted the x-values.

• No, she put the x-values in the numerator and the y-values in the denominator.

Find the slope represented in the table.
