1. The slope-intercept form of a line is shown below.

y = ms + 6

Here m represents the slope and b represents the y-intercept.

The slope of the line shows the rate of change in a linear equation,

y = 125 + 16

In the equation shown above, the slope is 12, and x represents every 6 minutes after 11:00a. m.

If for every 6 minutes, 12 pizzas are placed on the buffet, then for every 12 minutes, 24 more pizzas were set out on the buffet.
