a line represents a proportional relationship. which set of points could be on the line? a) (−2, (−4), (2, 1), (6, 3), (14,7) b) (6, 8), (4, 0), (18, 24), (20, 26) c) (3, 6), (4, 8), (9, 4), (11, 2) d) (1, 1), (2, 1), (3, 3), (4, 2)

the answer would be c:   ax + b = ax + c

step-by-step explanation:

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

1. 16.64

a^2+b^2=c^2

pr^2=pq^2+qr^2

pr^2=14^2+ 9^2

pr^2=196+81

pr= sqr root of 277

16.64

2. 11.31

c^2-a^2=b^2

18^2- 14^2=b^2

b^2=324-196

b=sqr root of 126

b=11.31

hope it ! (btw im in connections academy to, good luck! )
