Step 4: (if asked to "write in slope-intercept form"): Simplify by ___________ and solving for "y".

new

Ex 4: Write in point-slope form the equation of the line that has slope of -2 and goes through the point (3, -1). Then rewrite the equation in Slope-Intercept Form [y = mx + b].

y = mx + b

y = mx + bdistributing

Step 1: Identify the SlopeStep 2: Identify x1 and y1

Step 3: Plug into the point-slope formula [y − y1 = m(x − x1)]
