Rearrange x 7y-5 to make y the subject
Webbx - 7y = 5 y = 0.143x - 0.714 Find slope The slope of the line (m) is the steepness of the line. It is the change in the y coordinate divided by the corresponding change in the x coordinate. Simply plug in the coordinates from above and solve for m to get the slope for x - 7y = 5 m = (y 2 - y 1 )/ (x 2 - x 1) m = (-0.714 - 0)/ (0 - 5) m = 0.143 WebbI have to make x the subject of the following formulae: y=4x+7 7y-4x=6x-2 4y=1/4x 6(y-8x)=4x-2 y=√(7x+9) 0.5V= πd2x/4 I have no idea where to start, could you please explain how these are done.
