Jessica is babysitting to earn money for a new phone. She charges $12 per hour.

If x is the number of hours she babysits and y is the money she earns, identify the equation that models this situation.

• y = 10x

• y = x + 10

• x = 10y

• x = y + 10

What is the slope of the line?

• $\frac{1}{3}$

• $-\frac{1}{3}$

• 3

• -3

Sam & Katie are hiking down a mountain. They are descending the hill at a rate of 20 feet per minute. The graph represents their trip.

Which equation below represents their descent?

• y = 2x + 360

• y = 20x + 360

• y = -2x + 360

• y = -20x + 360

Notice triangle ABE.

Notice triangle ACD.

Which option best explains how the rate of change is consistent for descent.

• The slope from A to B is 8/8. The slope from A to C is 10/10. The slopes have different rise and run so the rate of change is not consistent.

• The slope from A to B is 8/8. The slope from A to C is 10/10. Since both slopes reduce to 1, the rate of change is consistent.

• The slope is negative.

• Both triangles end at point A.
