Answer:
ROCK 2.3 kg
is about 22.5N
Step-by-step explanation:
To convert kg>>>>N
You multiply by 9.8 (this is good for estimating, but use more decimal places like, 9.80665 for more exact calculations).
You can divide N÷9.8 to find kg

Step-by-step explanation:
I need more info if this does not workout...
If two line are perpendicular. The multiply of their slopes are equal to -1.
First line's slope is: -1/2x because if the line equation is form of y=ax+b a is slope.
Let say second line's slope is m
m.-1/2=-1 so m=2
y=ax+b is general form of linear function/equation. (a=slope)
y=2x+b
If this line passes through the point (2,-2),if we write -2 to y and 2 to x, the equation becomes true.
-2=4+b
b=-6
Thus,
y=2x-6 is true answer.
