WebLinear equation. (y = ax+b) Click 'reset'. Click 'zero' under the right b slider. The value of a is 0.5 and b is zero, so this is the graph of the equation y = 0.5x+0 which simplifies to y = 0.5x. This is a simple linear equation and so is a straight line whose slope is 0.5. That is, y increases by 0.5 every time x increases by one.
