Write the equation 2y − 4x = 5 in the form y = mx +b. y equals two x plus start fraction five over two end fraction y = 2x + 5 y equals minus two x plus start fraction five over two end fraction y = 2x + 5

Starting with 2y − 4x = 5, solve for y.  To do this, add 4x to both sides, obtaining 2y = 4x+5.  Divide both sides by 2, obtaining

y = 2x + 5/2 (answer)
