Finding Rate of Change/Slope and y-intercept

Master finding slope and y-intercept from equations, graphs, and tables. Write linear equations easily!

Identify the slope and y-intercept from an equation in Slope-Intercept Form. Take notes while you watch the video! WATCH THE VIDEO ABOVE FIRST!!Find the slope and y-intercept of each equation. In the equation y = 3x + 5, the slope is 3 and the y-intercept is (0, 5 ) In the equation y = -2x + 7, the slope is -2 and the y-intercept is (0, 7 ). In the equation y = 3 - 8, the slope is 3 and the y-intercept is (0, -8 ). Identify the Slope and the Y-Intercept From a Graph Take notes while you watch the video! But this graph has the coordinates on it also.... What is the slope? -4 -2.5 2 Identifying the slope and y-intercept from a graph.Look at the graph below. Find the slope and the y-intercept, then write the equation for the line in slope-intercept form. Write the equation without any spaces. The slope of the line is 4.The y-intercept of the line is the point (0, -4).The equation of the line is y=4x-4 The slope of the line is 1 y-intercept of the line is the point (0, 7).The equation of the line is y=1 The slope of the line is 1 y-intercept of the line is the point (0, 3).The equation of the line is y=1 The slope of the line is -1.The y-intercept of the line is the point (0, -6).The equation of the line is y=-1x-6. Given the Slope and the Y-Intercept, Write the Equation Take notes while you watch the video! Given the slope, m and the y-intercept, b, write the equation for each line. Match the slope, m and the y-intercept, b with the correct equation. slope = 1 y-intercept = -2 y = 1 - 2 slope = 3; y-intercept = 4 y = 3x + 4 slope = 5; y-intercept = 2 y = 5x + 2 slope = 4; y-intercept = 3 y = 4x + 3 slope = -5; y-intercept = -2 y= -5x - 2 slope = 1 y-intercept = -3 y = 1 - 3 I can determine the rate of change or slope and y-intercept of a line from tables and graphs and real-world problemsEssential Questions you should be able to answer after activity:1. How do you find slope of change and y-intercept from a table?2. How do you find slope and y-intercept from a graph?3. How do you find slope of change and y-intercept from a real world problem? Finding the slope and y-intercept in a table a graph. . Check out the following video and see what you can discover about Slope and y-intercept. How do you find the slope between two points on the graph? Did you already know this? Let's practice:What is the slope and y-intercept of the data in this table? The slope is 3 The y-intercept is -2. The slope is 4 The y-intercept is -2. The slope is -4 The y-intercept is -2. Let's try another one:What is the slope and y-intercept of the data in this table? The slope is 2. The y-intercept is 12. The slope is -2. The y-intercept is -6. The slope is 1 The y-intercept is -6.
