Which of the following statements best describes the graph of x + y =2? A) it is a line which intersects the y-axis at (2,2).

B) it is aligned joining the points whose x- and Y- coordinates add up to 2.

C) it is a line which intersects the x-axis at (2,2).

D) it is a line joining the points whose x- and Y- coordinates add up to 4.

Step-by-step explanation:

so x+y=2

a line would have to go 0,2 2,0

so the answer would be D

4x and 6y

im not sure though

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
