4a is the answer I believe you’re looking for
The slope of a line, denoted "m" is:
m=(y2-y1)/(x2-x1), where (x1,y1) and (x2,y2) are any two points on the line.
m=(-4--3)/(9-5)
m=-1/4
So the slope is negative one quarter.
The answer is -28
hope this helps :)
(can you please mark me as brainliest?)
I’m not sure if the 15 is the question number but if it is the answer is 32. use PEMDAS
What is 100% of the mass ?
