Answer:
line1:y=2x+3
Gradient1=2
Let line2 be the line passes through (-4,1)and perpendicular to line1.
Because line2 and line1 are perpendicular, (gradient of line2) (gradient of line1) =-1
Gradient of line2=-1/2
Equation of line2:y-y1 =m(x-x1)
:y-1 =(-1/2)[x-(-4)]
:(y-1)(-2)=(x+4)
:-2y+2 =x+4
:-2y+2-x-4=0
:-x-2y-2 =0
:x+2y+2 =0
*notes:gradient=m
Multiply lxw and divide by 2 from your anawer
the answer is B
P/s : i use my calculator
ok done. Thank to me :>
We know that each number can be divided by two to simplify.
6 / 2 = 3 and 8 / 2 = 4
By dividing, we are getting a simplified version of that fraction.
3 / 4
So Jeremy, in simplified terms, walked 3/4 of the way to school before running 1/4 of the rest of the way.
