How do you know when you need to find the point on the graph

The y-coordinate of a point is the value that tells you how far from the origin the point is on the vertical, or y-axis. To find the y-coordinate of a point on a graph:

Draw a straight line from the point directly to the y-axis.

The number where the line hits the axis is the value of the y-coordinate.

Looking back at the graph with our points B and D, we now identify the y-coordinate for each.

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
