Identifying slope and y intercept

What is the value of slope in this equation?

y=4x+13

• 16

• 13

• 4

• there is no slope

When finding slope you can look for words such as.....

• per, each

• incline

• constant, initial

• drop away

Which equation would best represent the following problem:

Devon went to the local nursery. They were having a holiday extravaganza! The entrance fee was $15 per person, to see each attraction he would need one ticket which sold for $3 per ticket.

• y=15+3x

• y=3x-15

• y=-3x+15

• y=15x-3

Which word problem would match the equation:

y=250-40x

• The rental service for boats required a $250 deposit and then charged $40 per boat.

• The car repair shop costs $40 for an evaluation and $250 per hour when fixing cars.

• The window replacement company charges a flat fee of $250 and each additional window would cost $40.

• The car service charges $250 for a month. As you use the car service the amount is deducted from the monthly service. Each time the service is used they charge $40.

Find the appropriate equation:

The shipping fee via US Priority Mail includes a $5 insurance fee and $6 per kilogram of the package. If an equation is made to calculate the shipping charge,

• y=6-5x

• y=5x+6

• y=6+5x

• y=6x+5

What is the value of the y intercept?

y=80-6x

• 6

• 80

• 6x

• -6
