Which statement best explains if the graph correctly represents the proportional relationship y = −2x?

a. it does not, the points shown would not be part of y = −2x.
b. it does not, proportions cannot be represented on a graph.
c. it does, all proportions can be shown on a graph of this line.
d. it does, the points shown on the line would be part of y = −2x.

So, it does, the points shown on the line would be part of y = −2x.

Step-by-step explanation:

1)The linear function is a decreasing one therefore it is graphed from 2nd Quadrant to 4th Quadrant. In addition to this, since is linear parameter b is equal to zero, the line crosses its origin. Finally, its slope is equal to -2.

2)We have (-1,2) and (2,4),  pointed out. Linear functions with b=0 are proportional ones. Proportional functions have its slope calculated by:

So, it does, the points shown on the line would be part of y = −2x.

answer: t=3

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
