Determine the slope of the line passing through the points (5,6) and (-5,-1)m=____

EleoNora [17]

GIVEN:

We are given two points on a line and these are;

$A=(5,6),\text{ }B=(-5,-1)$

Required;

We are required to determine the slope of the line passing through these points.

Step-by-step solution;

The slope of a line is given by the formula;

$m=\frac{y_2-y_1}{x_2-x_1}$

The variables are;

$\begin{gathered} (x_1,y_1)=(5,6) \\ \\ (x_2,y_2)=(-5,-1) \end{gathered}$

We can now substitute these into the formula and then simplify;

$\begin{gathered} m=\frac{-1-6}{-5-5} \\ \\ m=\frac{-7}{-10} \\ \\ m=\frac{7}{10} \end{gathered}$

ANSWER:

The slope of the line passing through the given points is;

$m=\frac{7}{10}$

Sue buys 5 pieces of fabric.Each piece is 1 7/10 yards long.What is the total length of the fabric she buys?One yard of the fabr

Bumek [7]

Answer:

1. 8.5 yards.

2. $42.5

Step-by-step explanation:

We have been given that Sue buys 5 pieces of fabric. Each piece is $1\frac{7}{10}$ yards long.

1. To find the total length of fabric bought by Sue we will multiply length of each fabric piece by 5.

$\text{Total length of the fabric}=5\times 1\frac{7}{10}\text{ yards}$

$\text{Total length of the fabric}=5\times \frac{17}{10}\text{ yards}$

$\text{Total length of the fabric}=\frac{17}{2}\text{ yards}$

$\text{Total length of the fabric}=8.5\text{ yards}$

Therefore, Sue bought 8.5 yards of fabric.

2. 1 yard of fabric costs $5.

So 8.5 yards of fabric will cost : 5*8.5

$\text{Total cost of the fabric}=5\times 8.5$

$\text{Total cost of the fabric}=42.5$

Therefore, the cost of total fabric bought by Sue is $42.5.
