dimension of the rectangle
Width = 8y-1.5
Length = 1.5y+9
Required
The expression to represents the Perimeter
Step two:
the perimeter of a rectangle is expressed as

collect like terms

Answer:
y = 8x+0
Step-by-step explanation:
The slope is
m = (y2-y1)/(x2-x1)
= (-8-0)/(-1-0)
-8/-1
8
The y intercept is 0 since it goes through (0,)
The slope intercept form of the equation is
y = mx+b
y = 8x+0
Answer:
8a+40
Step-by-step explanation:
8(a+5)
