What is the slope of line PQ?

Scilla [17]

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

<u>Part a) Find the slope of line PQ</u>

$P(-8,2)\ Q(4,2)$

substitute in the formula

$m=\frac{2-2}{4+8}$

$m=\frac{0}{12}=0$

Any line parallel to X-axis has slope equal to zero

so

the line PQ is parallel to the x-axis

therefore

<u>the answer Part a) is </u>

$0$

<u>Part b) Find the slope of line MN</u>

$M(8,6)\ N(8,-8)$

substitute in the formula

$m=\frac{-8-6}{8-8}$

$m=\frac{-14}{0}$

Anything divided by zero is undefined

m=undefined

therefore

<u>the answer Part b) is </u>

undefined

<u>Part c) How are the two lines related ? </u>

we know that

Any line perpendicular to X-axis has slope undefined

Because the term $(x2-x1)$ will always be zero

so

<u>the answer Part c) is</u>

the lines are perpendicular

grigory [225]

Answer:

yuki has spent 22 percent , Rosetta spent 20 percent

step by step explanation:

1) if £100=100percent

then £22=x percent

x=(22×100)/100=22 percent

2) if £140=100 percent

then £28= x percent

x=(28×100)/140

x=2800/140

x=20 percent
