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?
