My Real-Life Linear Equation
By Sarah Hall
My Linear Function is the Sound-Board of my Harp.
This is the harp I've played everyday at home since I was six.
The two points on the line are (4, 5) and (2, 4).
Equations of My Line.
Slope-Intercept Form: y=(1/2)x+3

Standard Form: (1/2)x-y= -3
Parallel and Perpendicular Lines.
Parallel Lines:
y=(1/2)x+72
y=(1/2)x-34
Perpendicular Lines:
y=(-2)x+235
y=(-2)x-83
