Answer:
8
Step-by-step explanation:
Use substitution: substitute each number from the set in for x, and see if the result from dividing is 45.
4
360/x=45
360/4=90
90 ≠ 45
Therefore, 4 does not make the equation true
8
360/x=45
360/8=45
45=45
Therefore, 8 does make the equation true.
16
360/x=45
360/16=22.5
22.5 ≠ 45
Therefore, 16 does not make the equation true.
So, 8 is the value that makes the equation true
The answer is X less than or equal to 1
Slope can be calculated using the formula: m= 
y1/x1 represents the first number in the bracket
y2/x2 represents the second number in the bracket
Calculation
m = 
m = 
m= 6/-12
m= -0.5 or -1/2
Therefore, the answer is B.
