Question

can someone help me understand how to find the slope of a line plzzzzzzzzzz

Answer 1

Give me the equation, I will guide you to find its slope..

Answer 2

If you can just write any equation in the form y = mx +c, then it gets easy to find the slope..

Answer 3

i have two points on a graph will that work??

Answer 4

Yeah why not...

Answer 5

Then just write those two points..

Answer 6

(2,3)(5,3)

Answer 7

Okay..

Do you know here, what is \(x_1, y_1, x_2\) and \(y_2\) ??

Answer 8

no

Answer 9

sorry

Answer 10

See coordinates of every point is written as : \(x, y\)

Do you know this??

Answer 11

yes i do the first # is always x right

Answer 12

Here x represents x coordinate and y represents y coordinate of that point...

Answer 13

ok

Answer 14

Yep..
So if you have point say (5,3)

Then can you tell me what is its x coordinate and what is its y coordinate??

Answer 15

the 5 is x and the 3 is y right ??

Answer 16

Yep..

Similarly if you have two points then,

You will write that points as : \((x_1, y_1)\) for first point and \((x_2, y_2)\) for second point..

Okay??

Answer 17

kk

Answer 18

Similarly, you have now two points : (2,3) and (5,3)..

Here can you tell me what are \(x_1, y_1, x_2, y_2\) ??

Answer 19

(2=x1,3=y1)(5=x2,3=y2)

Answer 20

So now you have just made it:

Formula for Slope when you are given with two points \((x_1,y_1) \) and \((x_2,y_2\)) is given by:

\[\large \color{green}{Slope = \frac{y_2 - y_1}{x_2 - x_1}}\]

Just use it buddy..

Answer 21

Just plug in the values and find slope..

Can you do it??

Answer 22

umm i think i can let me try it and get back to u

Answer 23

Take your time..

No hurry..

Answer 24

is it -3

Answer 25

Wait, let me check..

Answer 26

kk

Answer 27

No. how you got -3 ??

Answer 28

i did the equation ???

Answer 29

Just show your work, how you plugged in those values just show..
