Find the slope of the line without graphing using the 2 points below.

malfutka [58]

Answer: m=-11

Step-by-step explanation:

To find the slope of the line, you want to use formula $m=\frac{y_2-y_1}{x_2-x_1}$ . Since we are given two points, we can directly plug them in and solve.

$m=\frac{-21-(-10)}{4-3} =\frac{-11}{1} =-11$

Now, we know that the slope is -11.

admission to a carnival is $4 for children and $6 for adults. what is the ratio of the number of children to the number of adult

zvonat [6]

The ratio of the number of children to the number of adults in this group is 2 : 3

<h3>How to determine the ratio?</h3>

The admission is given as:

Children=4

Adult = 6

Express as ratio

Ratio = Children : Adult

This gives

Children : Adult = 4 : 6

Simplify

Children : Adult = 2 : 3

Hence, the ratio of the number of children to the number of adults in this group is 2 : 3
