What is the equation for a line that goes through (0,-1) and (3,1)

y=2/3x-1

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(1-(-1))/(3-0)

m=(1+1)/3

m=2/3

y-y1=m(x-x1)

y-(-1)=2/3(x-0)

y+1=2/3(x)

y+1=2/3x

y=2/3x-1

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
