Given : klmn is a trapezoid

kf=1, mf || lk, altitude - h

area of klmf = area of fmn



find : kn

KF=1                                         Given
MF || LK                                    Given
Altitude-h                                  Given
A-KLMF=A-FMN                     Given
KF*h= FN*h/2                          Area of Parallelogram
FN=2, KF=2                             Area of Parallelogram
KN=KF+FN=3                         Part-Whole Postulate

Where m is the slope of the line and b is the y-intercept of the line, or the y-coordinate of the point at which the line crosses the y-axis. to write an equation in slope-intercept form, given a graph of that equation, pick two points on the line and use them to find the slope. this is the value of m in the equation.
