... • To solve an equation for y means to rearrange the equation so the y is by itself on the left side of the equal sign. For example, in the equation y = 2x + 5, the y is by itself and the rest of the equation shows what y equals. • The standard form of a linear function is written as ax + by = c, whe ...
