Answer:
a. 0
Step-by-step explanation:
1. To find the slope given two points, use the following formula:

2.
would be the second y-value (in the second ordered pair), 2, and
would be the first y-value (in the first ordered pair), also 2.
3. Same for the x-values.
is -2 and
is 4
4. Now plug in the values.

5. This equals
which simplifies to 0
Answer:
Step-by-step explanation:
volume of the pool =50×15×3=2250 m³
7.5, because:
Ex: .1, 1 is in the tenths place because it is right after the decimal. The digit after 5 is 0, and that rounds down. 0-4 round down, and 5-9 round up. So, 0 would keep 5 as itself.
Answer:
The slop of line perpendicular to line y =
x - 2 is ( - 3)
Step-by-step explanation:
Given Line equation as ,
y =
x - 2
The equation of line is y = mx + c
Slop of this line (m1) = 
Now second line with slop (m2) is perpendicular to line first , then
(m1) × (m2) = - 1
So, (m2) =
Or , (m2) = 
∴ (m2) = - 3
Hence the slop of line perpendicular to line y =
x - 2 is ( - 3) Answer
