Which of the following ordered pairs are solutions to the equation y=−2x+6? (Select all that apply.) Select all that apply: (0,6) (1,4) (−2,−2) none of the above

(0,6)

(1,4)

Step-by-step explanation:

(0,6)

1. Plug in 0 for x and solve to see if 6 results for y

y = -2(0) + 6

0 + 6 = 6

y = 6

When 0 is plugged in for x, y equals 6 which makes (0,6) a solution.

(1,4)

1. Plug in 1 for x and solve to see if 4 results for y

y = -2(1) + 6

-2 + 6 = 4

y = 4

When 1 is plugged in for x, y equals 4 which makes (1,4) a solution.

(-2,-2)

1. Plug in -2 for x and solve to see if -2 results for y

y = -2(-2) + 6

4 + 6 = 10

10 ≠ -2

When -2 is plugged in for x, y does not equal -2 which means (-2,-2) is not a solution.

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
