What is the unit rate of change for Geraldo's savings?

Geraldo saves $300 every 2 weeks

Geraldo saves $600 every 4 weeks

Look at the graph. The slope of segment CA is -3/2. Which of the following is true about the slope of segment XZ ?

The slope of XZ is the same as the slope of CA , because the ratios of the corresponding sides of the triangles are equivalent.

The slope of XZ is the negative reciprocal of the slope of CA , because the triangles are flipped.

The slope of XZ is one-half the slope of CA , because the ratio of corresponding sides between the triangles is ½.

There is no relationship between the slope of XZ and the slope of CA .

Triangles QUS and RTS are graphed as shown. Which of the following best describes the slope of QS ?

The slope is -1, because the ratio of the vertical height to the horizontal length simplifies to -1 for both triangle QUS and triangle RTS.

The slope is 14, because the ratio of the vertical height tot he horizontal length for triangle QUS is 14/14.

The slope is 1, because the ratio of the horizontal length to the vertical height simplifies to 1 for both triangle QUS and triangle RTS.

The slope is -5, because the ratio of the horizontal length to the vertical height for triangle RTS is -5/5 .

The graphs of triangles LMN and NOP are shown. Which of the following best describes the slope of line LP ?

⅖, because the ratio of the vertical side length to the horizontal side length for both triangles simplifies to 2/5.

5/2, because the ratio of the vertical side length to the horizontal length for both triangles simplifies to 5/2.

2, because the ratio of the vertical side length of triangle LMN to the vertical side length of triangle NOP is 2.

½, because the ratio of the vertical side length of triangle NOP to the vertical side length of triangle LMN is ½.

What do you know about the relationship between the slopes of the hypotenuses of two triangles that lie on the same line on the coordinate plane, like in picture shown?

The slopes of the hypotenuses of the two triangles are the same because they are on the same line.

The slope of the hypotenuse on the larger triangle is greater than the slope of the hypotenuse on the smaller triangle.

The slope of the hypotenuse on the smaller triangle is greater than the slope of the hypotenuse on the larger triangle.

What are some other terms for the word "slope?" Choose ALL answers that apply.

Unit rate (if the slope has a denominator of 1; key words include each, every, and per)

Length of the line/Distance between two points on a line

Look at the graph shown. Which unit rate is best represented by the line shown in the graph?

Jerome purchases bananas for $0.60 per pound.

Laci purchases apples for $2.50 per pound.

Melissa purchases 2-liter sodas for $1.50 each.

Wyatt purchases potatoes for $0.80 per pound.
