Gradient of line = (4 - 1)/(2 + 3) = 3/5

So general form of equation: y = 3x/5 + c where c is a constant

or 5y = 3x + c' where c' = 5c is a constant

The point (2,4) is on this line

so 20 = 6 + c' so tha c' = 14

Therefore, the equation of the line is: 5y = 3x + 14

The equation of the line joining through -1 3 amd parallel to the line joining 6 3 2 -3?

To find the equation of a line parallel to another line, we need the same direction vector. The direction vector of the given line is (2, -3). Therefore, the equation of the line parallel to it passing through (-1, 3) is x = -1 + 2t and y = 3 - 3t, where t is a parameter.
