Alinear graph with a negative slope would indicate which of the following?
a. as the independent variable increases, so does the dependent variable.
b. as the independent variable increases, the value of the dependent variable remains the same.
c. there is no relationship between the independent and dependent variables.
d. as the independent variable decreases, the dependent variable increases.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
