x2-x1 =a+2-a=2
y2-y1= 3x2 +2 -3x1 -2= 3(x2-x1)=3*2=6
correct answer is C
if D, then
y2-y1=9(x2-x1)=9*2=18, so D is wrong
Perimeter of a rectangle = 2(l+w)
Length = 4-7(3x+4y)
=4-21x-28y
Width = 3x(-2y)
=-6xy
Perimeter
=2(4-21x-28y-6xy)
Answer = 8-42x-56y-12xy
Answer: D
Explanation:
Point slope form:
(y - y1) = m(x - x1)
Coordinate given = (2,-6)
Slope = 3/5
Thus:
(y -(-6)) = 3/5(x - 2)
y + 6 = 3/5(x - 2)
Answer:
16
Step-by-step explanation:
90/27 = 3
50/3 = 16
