Find the slope of the line passing through the points , −7,−7 and , −3,6 .

formula for finding slope is y2 - y1 over x2 - x1 so,

y2 is 6 and y1 is -7

x2 is -3 and x1 is -7

minus those

6 - - 7

-3 - - 7

you get 13 over 4

so 3 1/4

the perimeter is increased by a factor of 2

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
