Please help me! I need details. I will appreciate it very much and I will mark Brainllist! Please! ASAP

(1, 4), (2, 8), (3, 12)

Step-by-step explanation:

The ratio if the number if books to the cost in dollars is 1 : 4

To plot on a coordinate grid, we first look at the horizontal direction (x-axis)

Take the number of books to be values of the x-coordinate.

Start at the origin and travel the necessary distance to the left or the right then move up or down in the vertical direction to mark the y-coordinate.

The corresponding cost to be the values of the y-coordinate. Mark or plot at the intersection of the two numbers.

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
