Y = 3x - 2
This is the equation of a straight line that intercepts the Y axis at -2. It has a gradient of 3/1, meaning that for every unit moved to the right, the line rises three units up the y axis.

y = -0.5x plus or minus any number
(2, 11)
x + 2y = 27 2x - y = 19 y = 2x - 19 x + 2(2x - 19) = 27 x + 4x - 38 = 27 5x = 65 x = 13 y = 2(13) - 19 y = 7
-4
if x = 8in the equation y=2x/(4-2) -- y=8in the equation y=2x/4-2 -- y=2it really depends on how the equation is written, because that would depend on whether you divide or subtract firsty = ( (8^2) / (4) ) - 2y = ( (64) / (4) ) -2y = 16 -2y = 14
