Answer:
2x + 5y + 28 = 0
Step-by-step explanation:
since they are perpendicular,
m1 ×m2 = -1
5/2 × m2 = -1
m2 = -2/5
now,
y -y1 = M (x-x1)
y - (-4) = -2/5 ( x - (-4) )
y +4 = -2/5 ( x + 4 )
5 ( y +4 ) = -2 ( x+4)
5y +20 = -2x - 8
2x + 5y +20 + 8 =0
2x + 5y + 28 = 0
B. 5:10 because 15-5=10 which is the number of pencils with erasers and the 5 left are the amount of pencils which are missing an eraser
The measuring unit is the standard unit of a quantity

<h3>How to determine the unit of base 0.001</h3>
The basic measuring unit in base 7 is given as:
49 circles
The above can be represented as:
Base 7 = 49 circles
Represent the base with n.
So, we have the following rule
For measuring unit 0.001, we have:
Evaluate the square
This means that,
