Answer 2

IMPORTANT LINE RELATED EQUATIONS TO KNOW AND MEMORIZE

slope formula
m= slope/ gradiant -- same thing
\[m=\frac{y_2-y_1}{x_2-x_1}\]

standard formula
\[Ax+By=C\]

point-slope formula
\[y-y_1=m(x-x_1)\]

slope-intercept formula
b= y-intercept -- in the form of (0,y)

\[y=mx+b\]

Answer 3

read through that, if you still dont know how to calculated slope, say something

Answer 4

okay i m am reading it now, I will let you know if I understand it

Answer 5

use the slope formula.

Answer 6

okay i did is

m = (y2 - y1)/(x2 - x1)
m = (-2 - (1))/(4-2)
m = (-2 + 1)/(4-2)


so far i did it this way, is it correct? @completeidiot

Answer 7

if it correct then what do I do next?

Answer 8

m = (-2 - (1))/(4-2)

this part is correct

you dont need to switch the sign of 1

you just solve for m to get the slope,
because it is linear, the slope between all the points will be the same

Answer 9

thanks! So is -2/3 the answer then?

Answer 10

-3/2 not -2/3
