OBJECTIVE:USE THE SLOPE INTERCEPT FORM TO GRAPH A LINESlope Intercept Form

Slope & Y-Intercept

m = slopeb = y-intercept

Verify Points on a Line

Determine whether (3,-5)lies on the graph of y = -3x + 4

Verify Points on a Line

Determine whether (8,4)lies on the graph of 3y = 2x -1

Verify Points on a Line

Determine whether (5,-7)lies on the graph of 3y + 5x = 4

Graphing Steps1. Write the equation in slope intercept form2. Identify m and b3. Plot the y-intercept (0,b)

4. Start at the y-intercept,find another point on the line using the slope5. Draw the line

y = 5x -4Start at the point (0, -4)Plot another point on the line using the slope (m = 5)Rise five units upRun one unit to the right

Start at the point (0, 2)Plot another point on the line using the slope (m = -3/4)Rise 3 units downRun 4 units to the right

Graph Using m and b

m =-1b = 4

Graph Using m and b

m = 3/4b = -5

Graph Using m and b

m =-1/5b = 1
