Name: Date: Page 1 of 2 Practice with Slope-Intercept Form y = mx +b is the slope-intercept form of an equation: m is the slope and b is the y-intercept. Method for Graphing a Function in Slope-Intercept Form Start by plotting the point (0,b) which is the y-intercept. From that point, count the rise and run according to slope to obtain other points. Connect the points with a line. Do a quick check to see that your graph makes sense. If the slope is negative, is your line decreasing? If the slope is a number close to zero is your line relatively flat? 1. For each function find the slope, m, and y-intercept, b. Then graph each function. Label the coordinates (xy) of two points on your line. (b) y=D 글x-2 b= (a) y = x - : m= b= (d) y =x+3 b= b= (c) y = -6x+4: m= Ty Activity 4.4.3 CT Algebra I Model Curriculum Version 3.0 42
