For a relation to be a function, it must only have one y-value per x-value.

The top-left answer has two y-values on x=0.
The top-right answer has two y-values on x=-1.
The bottom-left answer has two y-values on x=2.

The answer is the bottom-right graph.

Determine the slope of the line that passes through the points (-2, 5) (1, -7)

Llana [10]

Answer:

-4

Step-by-step explanation:

<u>Given points </u>

(-2, 5) (1, -7)

<u>Use slope formula to find the slope</u>

m = (y2 - y1)/(x2 - x1)
m = (-7 -5)/(1 + 2) = -12/3 = -4

Slope is -4

The area of a cross section perpendicular to the base of a rectangular prism is 45 square inches. If the length and width of the

Naily [24]

The height of the prism is $2.25 \ in$

Explanation:

It is given that the area of the cross section of the rectangular prism is 45 square inches.

Length of the rectangular prism is $5 \ in$

Width of the rectangular prism is $5 \ in$

To determine the height of the prism, let us substitute these values in the formula $SA=(2l+2w)h$ , we get,

$45=(2(5)+2(5))h$

Multiplying the terms within the bracket, we get,

$45=(10+10)h$

Adding the terms within the bracket, we have,

$45=20h$

Dividing both sides by 20, we get,

$2.25=h$

Thus, the height of the rectangular prism is $2.25 \ in$

The graph shows a proportional relationship between the number of kilometers traveled by a bicycle (y) and the number of minutes

yaroslaw [1]

The unit rate of the bicycle is 0.3 kilometers per minute.

<h3>Linear equation</h3>

A linear equation is in the form:

y = mx + b

where y, x are variables, m is the rate of change and b is the y intercept (initial value of y).

Let y represent the km travelled by the bicycle after x minutes. From the graph using the point (0, 0) and (40, 12), hence:

Unit rate (m) = (12 - 0)/(40 - 0) = 0.3 km/min

The unit rate of the bicycle is 0.3 kilometers per minute.
