Hi!

<h3>To find the slope, use this formula</h3>

$\frac{y2-y1}{x2-x1}$

<h3>Put in the values</h3>

$\frac{4-(-3)}{5-(-2)}=\frac{7}{7}simplify=1$

<h2>The slope is 1 </h2>

Hope this helps! :)

The ratio of dogs to cats at an animal shelter is 33 to 22. How many dogs are at the shelter if there is a total of 3030 animals

Elena-2011 [213]

D : c = 33 : 22
where d is the number of dogs and c is the number of cats;
and: d + c = 3030
33 c = 22 d / : 11
3 c = 2 d
From the other equation: c = 3030 - d
3 * ( 3030 - d ) = 2 d
9090 - 3 d = 2 d
5 d = 9090
d = 9090 : 5
d = 1818
Answer: There are 1818 dogs in the shelter.
