Answer
its a cube whose side is 1 unit long .
And total surface area should be 6 square units .
as we can see
hope this helps
andddd yeaaaaaaa hope !!!!!!!
(x,y)
domain is inputs (normally x or first number)
range is outputs from the given domain (normally y or second number)
domain is just all the first numbers
range is all the second numbers
ignore repeats
domain: {0,4,5}
range: {2,3,5,7}
Answer:

The slope can be founded with this formula:

And replacing we got:

And the best answer for this case would be :

Step-by-step explanation:
For this case we have the following two points given:

The slope can be founded with this formula:

And replacing we got:

And the best answer for this case would be :

first, we can find the slope from the equation that is given buy solving the equation for y
3x+2y = 6
2y = 6-3x
y = 3-3/2x
y = -3/2x+3
now that the equation is in slope-intercept form, we can easily see that the slope of the given line is -3/2
perpendicular lines have slopes that are negative reciprocals, so we can just take the negative reciprocal of the slope we have
-3/2 → 3/2 → 2/3
the slope of the perpendicular line is 2/3
hope this helped
