If we reduce the slope between points b and c

6/10 divide the top and bottom by 2

3/5

A to B and B to C have the same slope

They are the same line, since point B is the same point

Which of the following sets would have a graph with an open circle on 5 and a ray pointing right on the number line?

vaieri [72.5K]

<h3>Answer: Choice C $\{x | x \in \mathbb{R}, \ x > 5 \}$ </h3>

The open circle means we do not include the endpoint, hence the use of a greater than symbol. If we were to include the endpoint, then we'd have greater than or equal to. We can rule out choice B due to this reasoning.

The ray pointing to the right indicates we are talking about x values larger than 5, so we can rule out choice A and conclude the answer is C.

Side note: The notation $x \in \mathbb{R}$ is saying "x is a real number"

The graph highlights two other points on the trend line. Use them to find another equation for the trend line shown for this sca

frutty [35]

Option A:

The equation for the trend line is y = 82x + 998.

Solution:

The points on the line are (2, 1162) and (11, 1900).

Here, $x_1=2, y_1=1162, x_2 = 11, y_2=1900$

Slope of the line:

$$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$$m=\frac{1900-1162}{11-2}$

$$m=\frac{738}{9}$

m = 82

Point-slope formula:

$y-y_{1}=m\left(x-x_{1}\right)$

$y-1162=82\left(x-2\right)$

$y-1162=82x-164$

Add 1162 on both sides of the equation.

$y=82x+998$

The equation for the trend line is y = 82x + 998.

Hence Option A is the correct answer.
