Answer:

y = -4

Step-by-step explanation:

First, let's find the slope. Since the line is horizontal, it's slope has to be 0 (this is because slope = rise/run, there is no "rise" in a horizontal line therefore the slope is 0)

Now, we need to find the y-intercept. This is where the line intercepts the y-axis. Looking at the graph, the line intercepts the axis at (0,-4), therefore the y-intercept is -4.

The equation would be:

y=0x-4

y=-4

Use one or more transformations to transform the pre-image (purple) onto the image (white).

Answer: This is a translation of 12 units to the right.

translation written (x,y) -> (x+12,y+0)

Step-by-step explanation:

Pick a point on the pre-image, and count how many squares it has to move to end up at the corresponding point in the image.

Add that value to the coordinate x for horizontal movement, here +12.

Add to the coordinate y for vertical movement. here 0.
