In this video we use slope-intercept form to draw the graph for x + y = 0. It we rearrange the equation x + y = 0 we can also use the slope intercept formula to draw the graph. The general...

Subtract x+2y=0 from x+y=0 by subtracting like terms on each side of the equal sign. Add x to -x. Terms x and -x cancel out, leaving an equation with only one variable that can be solved. …

Example: y = 2x + 1 is a linear equation: The graph of y = 2x+1 is a straight line. When x increases, y increases twice as fast, so we need 2x; When x is 0, y is already 1. So +1 is also …
