Please help :)
lets say uve got 2 pairs of coordinates of 2 points as (x_1 , y_1) and ( x_2 , y_2) then\[slope = \frac{ Y_{2} - Y_{1} }{ X_{2} - X_{1}}\]
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 ?
\[slope = \frac{ 1 - 2 }{ 3 - 0 } = ?\]
i don't get it....
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
