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

Point-Slope Form: y-5=(1/2)(x-4)

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
