The relationship between money earned and hours worked is linear. Joe computes the slope between (4, 30) and (12, 90), then computes the slope between (4, 30) and (10, 75). How do the two slopes compare?

The slope between (4, 30) and (12, 90) is greater because the ordered pairs are farther apart on the x-axis.

The slope between (4, 30) and (12, 90) is greater because the ordered pairs are farther apart on the y-axis.

The slope between (4, 30) and (12, 90) and between (4, 30) and (10, 75) is the same.

The slope between (4, 30) and (12, 90) is less because 4 is a factor of 12 and 30 is a factor of 90.
