Slope-Intercept Form

Linear Functions and Slope-Intercept Form. Watch the following video and then solve the exercises below. Fill in the blank with the answer you consider the right one. We can represent linear functions using the formula y = mx + b. This form is called slope-intercept form because it tells you the slope and y-intercept of a line.The variable mis the slope of the line.The variable b is the y-intercept.To graph a line using the slope-intercept form:1) First, plot the y-intercept (0, b) on the y-axis.2) Then, use the slope to count the rise and run to a second point. Slope Intercept Form Match the provided slope and intercept to the correct equation. m = 2, b = 3 y = 2x + 3 m = 3, b = 2 y = 3x + 2 m = 1, b = -4 y = x - 4 m = 0, b = 4 y = 4 y = -3x - 1 What is the slope? -1 -3 -1 (3, -1) What is the y-intercept? (0, -1) -3 -1 (3, -1) Match the equation to the graph. y = 1 x - 3 y = -3x + 4 y = 5x - 3 y = 1 x + 1 How well do you understand slope-intercept form? 1I do not understand. 2I understand a little bit. 3I understand. 4I understand perfectly. I can teach this in English!
