= Linear Equations in Slope-Intercept & Point-Slope Forms (The Trigs) =

Y=MX+B, That's the slope intercept equation you see M is the slope, it's an easy one Just remember that the rise goes over the run B is the y intercept, it's where the line crosses the y-axis Put them together and what have you got? You've got the slope-intercept equation **__Chorus:__** So let's talk lines and equations All about points and intercepts We'll find the slope and we'll use the X To find the Y that matches it   But what if we don't know B, the slope-intercept is out of reach So pick a point, and plug it in To the good old point-slope equation On the left you've got y minus y one on the right m times x minus x one So plug it in and solve for Y And watch the slope-intercept form appear before your very eyes
