B: y = 1/2x - 3/2

Step-by-step explanation:

Given points M (-3, 2) and N (1, 4):

The slope of line MN can be determined using the slope formula:

Therefore, the slope of line MN = 1/2.

By definition, parallel lines have equal slopes. Since the slope of line MN = 1/2, then it means that the slope of the other line parallel to line MN must also be 1/2.

Therefore, the correct answer is B: y = 1/2x - 3/2.

what is all that apply?

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
