How do you do the slope on a graph

1 answer:

4 0

I can't be entirely sure what you want to "do" about the slope,
but here is how to FIND it if you have the line on the graph:

-- You pick two points on the graph line.

-- Find the difference in 'y' between the two points.

-- Find the difference in 'x' between the two points.

-- The slope of the line between the two points is

(the difference in 'y')
divided by
(the difference in 'x') .

-- If the line on the graph is a straight line, then
the slope is the same everywhere on it.

Step-by-step explanation:

Given

Survey:

$Adults = 1000$

$Proportion = 34\%$

Required

What does 1000 represent?

First, we should know that 1000 adults were picked or selected from a larger number of adults.

This implies that:

The larger number of adults is the population and the 1000 selected adults represents the sample.

Find the slope of the line that goes through the given points (-4,11) (-12,-1)

Ira Lisetskai [31]

Answer:

Step-by-step explanation:

Use the slope formula to find the slope of a line given the coordinates of two points on the line. The slope formula is m=(y2-y1)/(x2-x1)

so it would be

11-(-1)/12--4)

which would be

12/16

to simplify that it is 3/4

Leilani practiced piano for 3/5 of an hour. Sarah practiced piano for 7/8 of an hour.

ivolga24 [154]

Answer:

The number of hours did Sarah practice more than Leilani is $\dfrac{11}{40}$ hours .

Step-by-step explanation:

Given as :

The time for which Leilani practiced piano = $\dfrac{3}{5}$ hours

The time for which Sarah practiced piano = $\dfrac{7}{8}$ hours

Let the number of hours did Sarah practice more than Leilani = T hours

<u>Now, According to question</u>

The number of hours did Sarah practice more than Leilani = $\dfrac{7}{8}$ hours - $\dfrac{3}{5}$ hours

Or, T = $\dfrac{35-24}{40}$ hours

Or, T = $\dfrac{11}{40}$ hours

So,The number of hours did Sarah practice more than Leilani = T = $\dfrac{11}{40}$ hours

Hence, The number of hours did Sarah practice more than Leilani is $\dfrac{11}{40}$ hours . Answer

Giselle works as a carpenter and as a blacksmith. She earns $20\$20 $20 dollar sign, 20 per hour as a carpenter and $25\$25 $25

malfutka [58]

C = # of carpenter hrs , b = # of blacksmith hrs

c + b = 30...c = 30 - b
20c + 25b = 690

20(30 - b) + 25b = 690
600 - 20b + 25b = 690
-20b + 25b = 690 - 600
5b = 90
b = 90/5
b = 18 <== hrs worked as blacksmith

c + b = 30
c + 18 = 30
c = 30 - 18
c = 12 <== hrs worked as carpenter
