Question

Please help :)

Answer 1

lets say uve got 2 pairs of coordinates of 2 points as
(x_1 , y_1) and ( x_2 , y_2)
then\[slope = \frac{ Y_{2} - Y_{1} }{ X_{2} - X_{1}}\]

Answer 2

so....
u can get the 2 pairs of coordinates from the graph
( 0 , 2 ) and ( 3 , 1 )
( x_1, y_1) and ( x_2 , y_2)
now plug them in to the above equation ... can u do that ?

Answer 3

\[slope = \frac{ 1 - 2 }{ 3 - 0 } = ?\]

Answer 4

i don't get it....

Answer 5

if u have the coordinates of 2 points...
here u can get the coordinates as ( 0 , 2 ) and ( 3, 1) ... both of these r 2 points on the given line

U can find the slope of the line by
\[slope = \frac{ Difference \ of \ y \ coordinates \ }{ Difference \ of \ x \ coordinates }\]

and

Difference of y coordinates = 1 - 2 ( these r the y coordinates in the example )
Difference of x coordinates = 3 - 0 ( these r the x coordinates in the example

so...
slope = -1/3
