Slope: m

Intercepts y intercept (b) The y intercept will be represented as b. the point(s) at which the relation crosses the y axis

Find the slope and the y intercept.

Slope-Intercept Form y = mx + b What is the slope and y intercept?

Using Slope-Intercept Form to Graph an Equation Step 1: Write the equation in slope-intercept form by solving for y. Step 2: Identify the y-intercept b and use it to plot the point (0, b) Step 3: Identify the slope m and use it to plot a second point on the line. (REMEMBER, ) Step 4: Draw a line through the two points. Step 5: Make sure your line is continuous.

Write a linear equation and graph the line. m = 3, b = -2

Write a linear equation and graph the line. m = -1, b = 3

Write a linear equation and graph the line. m = -2, b = -1

Write a linear equation and graph the line.
