Answer:

D, the horizontal line is a function

Step-by-step explanation:

To pass the vertical line test, a vertical line cannot go through the function more than once

A is a vertical line so it will fail the vertical line test

B will fail the vertical line test at many points. One example is at

x =0 where you can see it will intersect at two points

C will fail the vertical line test at many points. One example is at

x =0 where you can see it will intersect at two points

D is a horizontal line. This will pass the vertical line test

Answer:

Step-by-step explanation:

Subtract 100 from both sides to get x by itself.

x = 163

(Another way of writing this is "263 - 100 = " like you would see in elementary school.)

You go to an arcade and purchase a card with game credits. After playing 5 games you have 33 credits left. You play 4 more games

Answer:

$y=-3x+48$

Step-by-step explanation:

We will use slope-intercept form of equation to write our equation. The equation of a line in slope-intercept form is: $y=mx+b$ , where m= Slope of the line, b= y-intercept.

To write the equation that represents the number of credits y on the cards after x games, we will find slope of our line.

We have been given that after playing 5 games we have 33 credits left. We play 4 more games and we have 21 credits left. So our points will be (5,33) and (9,21).

Let us substitute coordinates of our both given points in slope formula: $m=\frac{y_2-y_1}{x_2-x_1}$ ,
