Question

what is the equation in piont slope form of the line passing through(-2,0) and (2,8)?

Answer 1

use this formula:
\(\LARGE \color{blue} {\sf slope = \frac{ y _{2}\ - \ y _{1} }{ x _{2} \ - \ x _{1} }}\)

Answer 2

and if you want the proof,i will prove it :)

Answer 3

got it?

Answer 4

yes kinda

Answer 5

why kind of?

Answer 6

prove it

Answer 7

ok,you know the slope is \(\sf \large\tan \theta\) ?

Answer 8

This is the point-slope form of the equation of a line.

\( y - y_1 = \dfrac{y_2 - y_1}{x_2 - x_1} (x - x_1) \)

Just plug in your points into \(x_1, y_1, x_2, y_2 \)

Answer 9

@mathstudent55 , using this formula is much better,i think!
finding the slope in your way , is difficult i think!

Answer 10

@joebrown1 , ok?
so the slope in mathematics - or in physics - is tan theta .

Answer 11

can you continue?

Answer 12

@joebrown1 , if you don't understand please just \( \sf \large {tell} \) me...:)
