"Perimeter" means the distance all around the figure.
So it's the sum of the lengths of all the sides.
Here are a few possibilities with Perimeter = 6 units:
-- a square, with every side 1.5 units long
-- a triangle, with every side 2 units long
-- a pentagon, with every side 1.2 units long.
-- a hexagon, with every side 1 unit long.
The sides don't all need to be the same length;
they just have to all add up to 6 units.
-- another triangle, with sides 1 unit, 2 units, and 3 units long.
The way I used to think to figure this out is to remember that a slope is "rise over run" or y over x (y/x). You'll want to find the change of y and the change of x. There is a change of -9 between 6 and -3. The change between -2 and 7 is 9 too. 9/-9 equals -1. So the slope is -1.
Answer:
Step-by-step explanation:
Math on it's own is not hard. It's the way teachers teach it. It also could be your brain, some peoples brain (like my own) aren't made for math where there is only one answer but for creative interprutive answers like philosophy and art. Some minds are good for sports. Find what your mind is good for and you never go wrong.
3x + 7y = 14
Subtract 3x from both sides
7y = -3x + 14
Slope is equal to -3.
