14.

Gabriel plots the points (-1, -2), (7, 2), and (-6, -9) on a coordinate plane. explain to him without graphing why the points do not lie along the same graph.

a)

The points do not lie along the same graph, because the slope of (-1, -2) to (7, 2) is not the same as the slope from (-6,-9) to (7, -2).

b)

The points do not lie along the same graph, because the slope of (-1, -2) to (7, 2) is the same as the slope from (-6,-9) to (-1, -2).

c)

The points do not lie along the same graph, because the slope of (-1, -2) to (7, 2) and the slope of (-6,-9) to (-1, -2) are undefined.

d)

The points do not lie along the same graph, because the slope of (-1, -2) to (7, 2) and the slope of (-6,-9) to (-1, -2) are 0.

15.

Alejandro draws a line through the points (9, -1) and (2, -1). What is true about all of the coordinate pairs of the points that make up this line?

a)

The slope from(9, -1) to (2, -1) is negative.

b)

The slope from(9, -1) to (2, -1) is positive.

c)

The slope from(9, -1) to (2, -1) is 0.

d)

The slope from(9, -1) to (2, -1) is undefined.

16.

María Gabriela did these calculations to find the slope of a line that goes through (0, 12) and (6, 4).  12  46  0=86=43\frac{12\ -\ 4}{6\ -\ 0}=\frac{8}{6}=\frac{4}{3}  

Veronica said she could tell this slope is incorrect, even without checking the calculations.

How did Veronica know the slope was incorrect?

a)

Veronica knows the slope is incorrect, because the graph has a negative slope and the calculations have a positive slope.

b)

Veronica knows the slope is incorrect, because the graph has a positive slope and the calculations have a negative slope.

c)

Veronica knows the slope is incorrect, because María Gabriela calculate the horizontal change over the vertical change.

d)

Veronica knows the slope is incorrect, because the slope of the graph is 0 and the calculations have a positive slope.
