 Question Samved: The line 3x/5 - 2y/3 + 1 = 0 contains the point (m, 2m-1). Calculate the value of 'm'.

Hi,

If a point with coordinates $(a,b)$ is on the graph then $x = a, y = b$ satisfies the equation of the graph. Since $(m, 2m-1)$ is on the graph this gives you an equation in the variable $m.$ Solve for m.
