I'm not sure for number one, but for number 2 the answer to that one is the second tallest on the chart or on the histogram. For number 3 I'm not sure because i cant see the numbers there too blurry. I'm sorry but i hope i got the second one correct.
Answer: m=1
Step-by-step explanation:
m = (y2 - y1)/(x2 - x1)
Where
y2=12
y1=9
x2=6
x1=3
so plug in your values in the slop formula:
m=(12-9)/(6-3)
=3/3
=1
Okay so basically domain =input and range =output. you can never have a negative number underneath the square root sign because it will make the answer imaginary (i), unless you are on that concept. Therefore the range is any number greater than 0. -> all real numbers greater than or = 0
for the range if you input 0 as x you will get -5, so any number you input after 0 will be greater than -5. so range is all real numbers greater than or equal to -5.
