wariber [46]

The slope will be -3/4
To find slope you just place the change in y over the change in x.
2- -1=3
0-4= -4
The slope is -3/4 which is the same as before

the graph shows the number of wimbledon championships of several countries. Write the ration that compares the championships won

arlik [135]

Answer:

The ratio that compares the championships won by Australia to the total number won by the United States is equal to $\frac{2}{5}$

Step-by-step explanation:

Observing the graph

we know that

The championships won by Australia are 6

The championships won by the United States are 15

To find out the ratio, divide the championships won by Australia by the total number won by the United States.

$\frac{6}{15}$

Simplify

Divide by 3 boths (numerator and denominator)

$\frac{2}{5}$

Convert to percentage

$\frac{2}{5}=0.40*100=40\%$

that means

For every 2 championships won by Australia the United States won 5

The championships won by Australia are 40% of the championships won by the United States
