Answer:
y -5 = (3/4)(x -6)
Step-by-step explanation:
Between the two points, the line has a rise of 6 and a run of 8. Thus, the slope is ...
... m = rise/run = 6/8 = 3/4
The point-slope form of the equation of a line with slope m through point (h, k) is ...
... y - k = m(x - h)
For point B, (h, k) = (6, 5), so filling in the values gives ...
... y - 5 = (3/4)(x - 6)
Alright, so let's make the length x and the width y. 2y=x, and xy=area. 2x+2y=perimeter. Plugging 2y=x into the perimeter equation, we get that 3x=perimeter=126, and x=126/3=42
Length=42ft, width=21ft
