We can add -2x to both members of 2x + y = 4 to get-2x + 2x + y = -2x + 4 y = -2x + 4. In Equation (2), where y is by itself, we say that y is expressed explicitly in terms of x.

Any line can be graphed using two points. Select two x x values, and plug them into the equation to find the corresponding y y values. Tap for more steps... Graph the line using the slope and the y-intercept, or the points.
