10/31 Review Part 1

Which linear equation best describes the graph above?

• y = 3/5x + 4

• y = 5/3x + 4

• y = 3/5x - 6.5

• y= 5/3x + 6.5

Answer explanation

We can see that the y-intercept (b) is 4. From there, using rise/run, we can see that we go up 3 and over 5, making the slope 3/5. Substituted into the equation y=mx+b, we would have the equation y=3/5x+4.

What is the equation of the given representation?

• y= - 5/2x - 1
• y= - 2/5x + 1
• y= - 5/3x - 1
• y= 3/5x + 1

What is the slope-intercept equation?

• y= 4x - 17

• y = 4x - 21

• y = 21x - 4

• y= -1x + 4

Carlos bought a video game. He made an initial payment of $75 to the store, and he will pay $5 each month until the game is paid off.

Which equation represents the relationship between m, the number of monthly payments Carlos has made, and t, the total amount that Carlos has paid the store?

• t = 75m + 5

• t = 5m - 75

• t = 75m + 80

• t = 5m + 75

Ashley is saving $18 that she earned for babysitting. She earns $7 every week for doing chores at home, which she also saves.

Which function can be used to find t, the total amount of money Ashley will have saved at the end of w, weeks of doing chores?

• t = 7w + 18

• t = 18w + 7

• t = 25w

• t = 18w

What is the correct slope-intercept form?

• y = mx + b

• y = mb + x

• y = x

• y = -mx + b

What is the slope intercept equation for this table?

• y=2x + 7

• y = -2x +3

• y= 3x + 3

• y= 7x + 2

The table shows the amount of money Rodrigo saves over several days at his new job.

Which equation represents how much money ,y, Rodrigo will save after working for x days?

• y = 24x - 10

• y = 24x + 10

• y = 10x + 24

• y = 10x - 24
