Q1: Find the slope of the line passing through the pairs of points and describe
the line as rising, falling, horizontal or vertical. (2,1),(-3,1)

m=0

horizontal line

Step-by-step explanation:

Given two points, we can find the slope from

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

   = (1-1)/(-3-2)

   =0/-5

The slope is 0

The line is horizontal

slope = 0 , the line is horizontal

Step-by-step explanation:

The formula for calculating slope is given as :

slope =

substituting into the formula , we have

slope =

slope =

slope = 0

since the slope is 0 , then the line is horizontal

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
