Which of the points shown below are on the line given by the equation y= 4x?
Check all that apply.

Step-by-step explanation:

My English is poor. But I thought it's B and C. Because 4=4*1 and -4=4*(-1).

The answer to your question is Points B and C.

Step-by-step explanation:

Data

Equation     y = 4x

Process

1.- Point A. (4, 4)

Substitute point A in the line and simplify

                   4 = 4(4)

                   4 ≠ 16               This point is not a solution

2.- Point B. (1, 4)

                   4 = 4(1)

                   4 = 4                This point is a solution

3.- Point C. (-1, -4)

                  -4 = 4(-1)

                 -4 = -4                This point is a solution

4.- Point D. (1, -4)

                  -4 = 4(1)

                  -4 = 4                This point is not a solution

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
