Perpendicular means the slopes are opposite inverse of each other
If line a is slope 2, the perpendicular line to Line a would have a slope - 1/2
Difference in y over difference in x gives slope. If they are opposite inverse values the lines are perpendicular. ( in this case the answer is true.)
Yep! the plotted points are (2,1) and (0,5) the slope is -2
Answer:
120 000 m^2
Step-by-step explanation:
I ASSUME you're being asked to convert from km^2 to m^2.
For this you need to identify the conversion rate, which is 1 000 000 m^2 / 1 km ^2. Multiply by the thing you're converting from and cancel the units.
(1 000 000 m^2 / 1 km ^2) x 0,12 km^2 = 120 000 m^2 (the km^2 cancels out, leaving you only with your target unit of m^2)
Because it is like having a unit of measurement that is set
lets say that in a certain country, one serving of bread is 1/2 of the standard loaf
and if you have 3 servings, you have 3/2 loaf so the bottom number tells you how many parts out of 1 whole you have
The answer is (x,y) = (-2, 16)
do you need an explanation as well?
