N is an interger what are the possible values of n A-, -2 ,-1, 0, 1, 2 ,3 ,4 ,5 ,6 B-, -1 ,1 ,2 ,3, 4, 5 ,6 C-, -2, -1 ,0 ,1, 2, 3 ,4, 5 D- ,-2 ,-1 ,0, 1 ,2, 3, 4, 5, 6, 7 E-, -1 ,0 ,1 ,2, 3 ,4 ,5 ,6

All options have possible values of an integer

Explanation:

From the above options given all options are integers. An integer is a whole number, that is a number that is not a fraction or a decimal number. An integer can be negative, positive or zero such as the above given numbers. Here there are no fractions such as 1/4 or improper fractions as 1 3/4 or decimal numbers as 2.543, therefore all options are correct.

the correct answer is option c.   3

step-by-step explanation:

points to remember

equation of the line with coordinates (x₁, y₁) and (x₂, y₂) is given by,

slope m = (y₂ - y₁)/(x₂ - x₁)

from the figure we can see a line with two coordinates given

to find the slope of given line

here   (x₁, y₁)   = (-1, -1 ) and (x₂, y₂) = (1, 5)

slope m = (y₂ - y₁)/(x₂ - x₁)

  = (5 - -1)/(1 - -1)

  = (5 + 1)/(1 + 1)

  = 6/2 = 3

therefore the correct answer is option c.   3

so, converting firstly the mixed fractions to improper fractions and then "adding".
