Explanation: There are many patterns in math, algebra and geometry. One of the patterns is called, the Slope-Intercept form. It is written as y = mx+b and is the "equation of the line". Notice the coefficient of 'y' must be '1'. When an equation is written in this pattern, the number 'm' represents the slope of the line and the 'b' represents the y-intercept. Observe these:
y = 3x + 5 The slope is 3 and the y-intercept is 5.
y = -3x The slope is -3 and the y-intercept is 0.
y = 5 The slope is zero and the y-intercept is 5. Since the slope is zero, the line will be a horizontal line.
Directions: For each equation, identify the answer that correctly lists the slope and y-intercept, in this order. First, strive for accuracy, then strive to increase your speed. Good luck and I hope you enjoy the challenge!
