Question

For the proportional relationship y = 2x, what is the ratio of vertical change to horizontal change?
A. 2/1 The graph increases from left to right.
B. 2/0 The graph increases from left to right.
C. 2/1 The graph decreases from left to right.
D. 2/0 The graph decreases from left to right.

Answer 1

slope as a proportion is rise/run

so write the slope of the line 2... as a fraction.... 2/1

so

\[\frac{rise}{run} = \frac{2}{1}\]

positive slopes go from lower left to upper right.

Answer 2

is it C then?

Answer 3

here is a line with a positive slope

Answer 4

then it is c? it decreases?
