You would need the 3rd side length of the triangle, in order to find the area.
S.I = PxRxT / 100
Therefore
S.I.= $10000x3x6/100
=$900
The rate of change is the slope...and in y = mx + b form, the slope is in the m position. So we need to put the equations in y = mx + b form.
A. 6x - 7y = 21
-7y = -6x + 21
y = 6/7x - 2....so the slope here is 6/7 or 0.857
B. y = 2x - 2....this is already in the form we need...the slope is 2
C. (2,7)(3,13)
slope = (13-7) /(3-2) = 6/1 or just 6
the slope with the greatest rate of change is gonna be the one with the highest slope......and that would be C.
The ordered pair (2,0) represents the equation 3y+4x= 8
