I hope this helps - it depends what you doing for it to be negative or nonnegative.. :)
For this case we have that by definition, the equation of a line in the point-slope form is given by:

Where:
m: It is the slope of the line and
is a point through which the line passes.
We have the following equation of the slope-intersection form:

Where the slope is 
By definition, if two lines are perpendicular then the product of their slopes is -1.
Thus, a perpendicular line will have a slope:

Thus, the equation will be of the form:

Finally we substitute the given point and we have:

Answer:
Option B
Answer:
1900
Step-by-step explanation:
so lets let x represent the total chips that in the bag.
We know that each chip weight 0.12 grams, and there are 228 grams in total. ok so, 0.12x=228
Divided 0.12 to each side
0.12x/0.12=228/0.12
x=1900 chips Which means there are 1900 chips in the bag. I hope this helped you<3 sorry if it didnt:(
