How do you find a slope of a line in a coordinate plane?

Question

homework

Answer 1

You would get two points on a graph and then divide the rise over the run.The two points have to be right after each other such as," the two cordinate pairs,{1,6} and {2,12}.You cant get two cordinate pairs that are like, {3,36} and then {10,120}. and the two cordinate pairs can be something like, {10,120} and {11,132}

Answer 2

Find two points of the line and use equation (y2-y1)/(x2-x1)=x (slope). The values of y2,y1,x2,and x1 come from when you assign each x and y coordinate in the points the value.
Example) points: (3,4) and (5,6) are on the same line. I assign the values x1 to 3 and y1 to 4. While I assign x2 to 5 and y2 to 6. so plug each into equation to get an answer of slope(x0=1.
( 6-4 ) / (5-3) = 2 / 2 = 1

Hope that helps!!!! Good luck!!!

Answer 3

In cartesian coordinates

if you have a line joining two points A = (x1, y1) and B = (x2, y2)

The slope is the change in the y-coordinate divided by the change in the x-coordinate when travelling from A to B.

(y2-y1) / (x2-x1)

Answer 4

Use the slope formula: m= (y2-y1)/(x2-x1)

For example, for the line with coordinates (0,2) and (4,6) you would place 6 (y2) minus 2 (y1) over 4 (x2) minus 0 (x1)

It would look like this:

6-2
------
4-0

Do your math, and the slope would be:

4
---
4

Which would be 1. So your slope is one.

Answer 5

-2/6 or -a million/3 You calculate it by potential of determining the upward thrust, this is how lengthy it runs vertically. then you definately exercising consultation the run, this is how lengthy it runs horizontally. then you definately positioned the upward thrust over the run in fraction type, this is 12/6 then simplify by potential of dividing by potential of two and also you get -a million/3.

Answer 6

find two points on the line and then use the slope formula
The two points:
(x1, y1) (x2, y2)
you put them in the...
Slope formula:
(y2-y1)/(x2-x1)

**the numbers are subscripts

Answer 7

I believe slope = rise / run

Answer 8

rise over run

take 2 points on the line. from the bottom point, rise / run = slope
algebraicly:
(a, b) and (c,d) are the two points
slope = a-c/b-d

Answer 9

Y1-Y2/X1-X2=SLOPE
