Finding the equation of a line from the slope and a point
Looks like: Find the equation of a line with a slope of 2 that goes through the point (-4, 3)
Step
/ Description/Rule/PictureStep 1 / Take inventory: What do you know? / m=______x=______y=______
Step 2 / Plug in: to the slope-intercept equation: y = mx + b / y = mx + b
____= ___*___ + b
Step 3 / Simplify and solve for b (beginning point)
Step 4 / Plug m and b into your slope-intercept equation: y = mx + b / m = ____ y = mx + b
b = ____
