Brick-Moving Process and Linear Functions

The video tutorial explains how to solve a problem involving moving bricks using a wheelbarrow. It starts with a setup of the problem, where 845 bricks need to be moved. The tutorial then calculates the rate of moving bricks per hour, which is the slope of a linear equation. It also determines the number of bricks moved by hand, which is the y-intercept. The linear equation is formulated, and finally, the total time required to move all bricks is calculated.

What prompted the decision to use a wheelbarrow for moving bricks?

• The backyard was too far from the driveway.

• The number of bricks was too large to move by hand quickly.

• The wheelbarrow was already available at home.

• The bricks were too heavy to lift by hand.
