Equations written in Slope-Intercept Form look like y = mx + b and tell two things about the graph of the equation. The 'm' is the slope and the 'b' is the y-intercept. The 'y' intercept means the ordered pair (0, b). From that point, the line follows the slope, 'm'. The slope is best considered to be a fraction of the vertical change over the horizontal change. When the slope is positive, the line slopes up to the right. For the equation y = 4x - 2, the 'm' is 4/1 and 'b' is - 2. When the slope is negative, the line slopes up to the left. For the equation y = - 3x the ''m' is - 3/1 and the 'b' is 0, which means the line crosses at (0,0). When the slope is zero, the line is horizontal and the equation looks like y = number.

Analyze the given equation and decide which shows the graph of the equation. Strive first for accuracy and then strive to increase your speed. Good luck and enjoy the challenge!
