Converting between Standard form and Slope-Intercept form Graphing Unit

Slope-Intercept Formula This formula will be used to ___________and _____________ linear equations. To be able to use this formula, the equation you are graphing must be in this format!! This means to ______________________________________. write graph Solve for “y”

Slope-Intercept Form y = mx + b “x” and “y” have to be on opposite sides of equation STEPS TO SOLVE FOR “Y” Add/Subtract the term that is on the same side of the equation with y Divide by the number in front of y

Find the slope and y-intercept. 4) 5x - 3y = 6 Write it in slope-intercept form. (y = mx + b) 5x – 3y = 6 -3y = -5x + 6 y = x - 2 -3 -3 -3 m = b = -2

Find the slope and y-intercept. 5) 2y + 2 = 4x Write it in slope-intercept form. (y = mx + b) 2y + 2 = 4x 2y = 4x - 2 y = 2x - 1 2 2 2 m = 2 b = -1

Example 1 & 2 Write in slope-intercept form You try it
