Which point lies on the graph of y = - 2? A. (10, -10)
B. (-8,-8)
O C. (-6, -6)
D: (-4,-4)

Step-by-step explanation:

None of them.

Any point on y = -2 has a notation of (x,-2). Every x value has a y value of - 2.

None of the given points do. Therefore none of the points are on the line y = - 2

the answer is 13 cm

< 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)
