Answer:its a zero slope or you can do x2-x1 and y2-y1 and if its an even fraction try simplifying it .
Step-by-step explanation:
Basically expand
use FOIL (a way to remember distributive property)
first outer inner last
that is th eorder to multiply them
First: x times 2x=2x²
Outer: x tmes 9=9x
Inner: -8 times 2=-16x
last: -8 times 9=-72
add them
2x²+9x-16x-72
2x²-7x-72
Answer:
0.64
Step-by-step explanation:
Find the number in the hundredth place 4 and look one place to the right for the rounding digit 1
. Round up if this number is greater than or equal to 5 and round down if it is less than 5
