Answer:

The answer is A

Step-by-step explanation:

By looking at the graph, the y-intercept is -1. So, the answer must be A or C.

A park is mapped on a coordinate plane, where C1, C2, C3, and C4 represent chairs and SW1, SW2, and SW3 represent swings. How fa
serg [7]

Answer:

Option (B)

Step-by-step explanation:

To calculate the distance between C2 and SW1 we will use the formula of distance between two points (x_1,y_1) and (x_2,y_2).

d = \sqrt{(x_2-x_1)^{2}+(y_2-y_1)^2 }

Coordinates representing positions of C2 and SW1 are (2, 2) and (-6, -7) respectively.

By substituting these coordinates in the formula,

Distance between these points = \sqrt{(-6-2)^2+(-7-2)^2}

                                                     = \sqrt{(64)+(81)}

                                                     = \sqrt{145} units

Therefore, Option (B) will be the correct option.

Determine whether each equation represents a proportional relationship
wlad13 [49]

Hey there! I'm happy to help!

A proportional equation follows the form y=kx, where k is the constant of proportionality.

Answer 1 is wrong because there is something added.

2 is correct as it follows this format.

3 is incorrect as it does not follow this format.

4 is correct as it follows the format (k is 1)

5 Is correct because it follows this format.

6 is not correct because there is a 1 added, which does not follow the format.

Therefore, the correct answers are 2, 4, and 5.

Have a wonderful day! :D
