well, the assumption is that is a rectangle, namely it has two equal pairs, so we can just find the length of one of the pairs to get the dimensions.
hmmmm let's say let's get the length of the segment at (-1,-3), (1,3) for its length
and
the length of the segment at (-1, -3), (-4, -2) for its width

Answer:
$0.20
Step-by-step explanation:
so you have 16 ounces of jam. i personally like jelly, but that's besides the point lol
so for those 16 ounces, you paid $3.20 for them.
unit price is just a term for the price of 1 item or measurement. you can use this to find out what product you are purchasing has the better deal, because you always want more product, for less money.
you should take the amount of money you are spending, and divide it by how many total ounces it has.
$3.20 / 16 = 0.20
this means that 1 ounce of jam costs $0.20
you can check your work by multiplying the price of one ounce, by how many ounces the jar is.
.2 * 16 = 3.20
i hope this was helpful to you and i explained well enough!
stay safe!!

Answer:
-2x - y = -5 in slop intercept form would be <u>y = -2x + 5 </u>
Step-by-step explanation:
-2x - y = -5
first add -2x to the left side to move it to the right side because whatever you do to one side u do to the other.
-y = -5 + 2x
divide by -1 on the whole equation
y = -2x + 5 is your answer.
