Step-by-step explanation:

Hello!

The vertical line test is a method to test if a graph is a function or not.

Given a graph, we can draw a vertical line anywhere on the graph. If the line intersects two or more points on the graph, it is not a function.

<h3>Reasoning</h3>

If the line passes through 2 or more points, it means that there are multiple values for the same x-value.

When you have a function, you can substitute a value for x to get a unique y-value. Having two intersections means that there are two values for one x-value.

Find the coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1)
Flauer [41]

Answer:

The coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1) are \mathbf{(13,\frac{-9}{2})}

Step-by-step explanation:

We need to find the coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1)

The midpoint of line segment can be found using formula:

Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})

We have x_1=14, y_1=-8, x_2=12, y_2=-1

Putting values and finding midpoint

Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})\\Midpoint=(\frac{14+12}{2},\frac{-8-1}{2})\\Midpoint=(\frac{26}{2},\frac{-9}{2})\\Midpoint=(13,\frac{-9}{2})

So, the coordinates of the midpoint of a line segment with the given endpoints (14,-8), (12,-1) are \mathbf{(13,\frac{-9}{2})}

Abby's school is 6 blocks west of her house. Her mother works at a store that is 4 blocks east of her school. Use a number line
faltersainse [42]

Answer:

<h2>10</h2>

Step-by-step explanation:

Let us give a proper illustration in the number line

let H be Abby's house

and S be the school

let W be her mother's work.

kindly find attached a rough sketch of the number line for your reference

Question:<em> What value represents the difference in position between Abby's house and her mother's store?</em>

basically, the distance between two points on a number line is the difference between the points.

So the value that represents the position between Abby's house and her mother's store is the distance between the two points.

= 4-(-6)

=4+6

=10
