Which axis is parallel to y=-1?

y axis

Step-by-step explanation:

When you set up an ordered pair, yi always has to be - 1 and x can be anything. To show you what this means, draw an x,y axis.

Plot a few points. Try these (0,-1) (2,-1) and (-2,-1) Now join them. They make a straight perpendicular line.

The line is parallel to the y axis.

A line parallel to the x axis has all the x's the same.

(-1, 1), (-1,2) (-1,4)

your answer is the last one

step-by-step explanation:

divide the length of a'c' by the length of ac to get a scale factor of two

& then reflect vertically (over the y-axis)

so your answer is dilation by a scale factor of 2 followed by reflection over the y-axis

i believe the correct answer is b.
