# how do you find slope ?

what is the slope of the line whose equation is 3x-2y=12?

thanks i could really understand this problem now anyway could any one help me with this ... what is the slope of the lines that passes through points (4,5) and (6,1)

Hi Fanny;
3x-2y=12
The equation is in standard form...
Ax+By=C, A>0
Slope is -A/B
-(3/-2)
A negative of a negative is positive....
3/2

You can just choose 2 points on the line, and get the slope by

m =   ( Y2 - Y1 ) / (X2 - X1 )

Intercepts :   ( 0 , -6 )   ( 4, 0 )

m = 0 - ( - 6) = =
4  -  0       4     2

Re arrange the equation to slope intercept form
y=mx + b where m is slope and b is y intercept

3x - 2y =12

-2y = 12 - 3x
2y = 3x -12
y = 3/2x  - 6

m = slope = 3/2
