The black line is the graph of y=x. which of these equations could represent the blue line?

Here we can see that the blue line cuts exactly half way through the angle that the black line makes with x axis

That is all the x values are halved

Which implies all the x value of the black line are divided by 2 to form the points on the blue line

so that give us the function

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
