What is the slope of the line? PLEASE PLEASE HELP FAST!
3241004551 [841]

Answer:

slope = 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (1, 2) ← 2 points on the line

m = \frac{2-0}{1-0} = \frac{2}{1} = 2

A carpenter is making a table that will be 45 inches wide. He is gluing boards together. Each board 3¾ inches wide.
Snowcat [4.5K]
3 3/4 inches are equivalent to 3.75 inches:3 3/4 = 3.75. Divide 45 inches by 3.75 to see how many boards are needed: 45 / 3.75 = 12. To check: 3.75 x 12 = 45 inches. So, 12 boards are needed.

PLS ANSWER what is the rate of change for these tables please answer in y over x form
Airida [17]

Answer:

1)\frac{-36}{5}

2)\frac{42}{5}

3)\frac{96}{1}

4)\frac{202}{2}

Step-by-step explanation:

Given is four pair of coordinates.

We have to find rate of change for these.

'Rate of change' is nothing but slope that is calculated as,

\frac{rise}{run} = \frac{y2-y1}{x2-x1}

1)

\frac{y2-y1}{x2-x1} \\\frac{12--24}{-6--1} \\\frac{36}{-5}\\\frac{-36}{5}

2)

\frac{6-48}{-3-2}\\\frac{-42}{-5}\\\frac{42}{5}

3)

\frac{-6-90}{3-4}\\\frac{-96}{-1}\\\frac{96}{1}

4)

\frac{-10-192}{6-8}\\\frac{-202}{-2}\\\frac{202}{2}

Therefore these are the required \frac{y}{x} form.
