Slope - Intercept Form Part 2

A sales associate is given a $500 hiring bonus with a new job. She earns an average commission of $250 per week

A farm has 75 acres of wheat. The farmer can harvest the wheat from 12 acres per day

For babysitting, Nicole charges a flat fee of $3, plus $5 per hour.

A taxi charges a flat rate of $3, plus an additional $1.50 per mile.

The cash register subtracts $2.50 from a $25 Coffee Café gift card for every medium coffee the customer buys.

Which of the following situations could be descried by the equation y= -25x + 120

• There are 120 people in the football stadium, and 25 more are entering each hour.
• A plumber charges $25 for a house call and $120 per hour.
• A teacher has 120 students. Her third period has 25 students
• There are 120 gallons of water in a tank. It releases water at a rate of 25 gallons per minute

Sally plans to walk 12 miles every week. Write an equation to represent this situation.

• y = 12x

• y = 12x + 12

• y = 10x + 2

• y = 2x + 10

Write the equation in slope-intercept form: 3x + y = 12

• y = -3x +12
• x = y + 4
• x = y + 12
• y = 3x -12

Write the equation in slope-intercept form: 2x + y = 41

• x = 2y + 41
• y = 2x -41
• y = -2x + 41
• x = y -39

Rewrite the equation into slope intercept form.

3y-2x=9
