Slope-Intercept Form

1) Listen to the audio.2) Complete the sentences. 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!
