Answer:
y= -2x-5
Step-by-step explanation:
First find the gradient of the first line
m=
m=
m=1/2
From this we can find the gradient of the perpendicular line, or the normal.
m1 × m2 = -1
Replace m1 with 1/2
1/2 × m2 = -1
m2= -2
Substitute values into
y-y1=m (x-x1)
y-3=-2 (x+4)
y-3=-2x -8
y=-2x-5
Answer:
2 + -2
= 0
Step-by-step explanation:
1st step convert into improper fraction:
===> 2 + -2
===> +
2nd step now adding the numbers:
( Plus sign and minus sign multiplies and hence the plus sign changes to minus)
===>
Therefore the sum of 2 + -2
= 0
