HW Review: Contracts and Materials are due Monday Regents packet is due Tuesday

Big Ideas: Sometimes, the equations are not in y = mx + b form You must have them in y = mx + b form to find the slope and y-intercept

Example #1: This isnt in y = mx + b form, so you need to get y by itself Divide everything by 2, then you can identify slope and y - intercept

Example #2: Given: 2y + 2 = 4x Identify: Slope and y-intercept, then write the equation of the line in slope-intercept form Subtract 2 from both sides Then, divide everything by 2 Then, identify slope and y-intercept
