Write a ratio expressing the slope of line n.

Mathematics

Arada [10]3 years ago

The slope<span> or gradient of a line is a number that describes both the direction and the steepness of the line. To calculate the slope of a line, you take the ratio of the change of the two points. It is expressed as follows:

slope = </span>Δy / Δx
slope = y2 - y1 / x2 - x1

You take two points from the graph and calculate using the equation above. Hope this helps. Have a nice day.

Alejandro uses the steps below to convert
dezoksy [38]

Answer:

The division was computed incorrectly.

Step-by-step explanation:

Given

Workings:

\frac{5}{8} to percentage

\frac{8}{5} = 1.6 = 160\%

Required

Explain his error

The question says 5/8

Instead, Alejandro's working shows 8/5.

This working is done in an incorrect order and the correct solution is:

Let

x = \frac{5}{8}

Solve the fraction

x = 0.625

Multiply by 100%

x = 0.625 * 100\%

x = 62.5\%

<em>Hence, option (a) is correct.</em>

Find the equation of a line that passes the points (5, -9) and (0, -3)
kobusy [5.1K]

Answer:

y = -6/5x - 3

Step-by-step explanation:

Point Slope Form:  (y - y1) = m(x - x1)

<u>Step 1:  Find Slope</u>

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

m = \frac{-3 - (-9)}{0 - 5}

m = \frac{-3 + 9}{-5}

m = \frac{6}{-5}

m = \frac{-6}{5}

<u>Step 2:  Plug into Point Slope Form</u>

(y - (-3)) = -6/5(x - 0)

y + 3 - 3 = -6/5x - 3

y = -6/5x - 3

Answer:  y = -6/5x - 3

Line CD contains points C(7, 4) and D(6, 1). Line JK is parallel to line CD. Which two points lie on line JK?
Andru [333]
From 6,1 to 7,4 
We can determine the slope of the line
rise/run
3/1=3

Now we know the slope of the line, a line parallel to it must obtain the same slope, therefore, I tried to see if the increase in y is three times the increase in x
I found the true pair to be A

(-4,1) and (-2,7)
