Pls help me with these questions

                                                 Question # 7

x    -1     0     1      2      3       4

y     -5    1     7     13    19      25

From the table, it is clear that x and y change at a constant rate, it must be a linear function.

Determining the slope between the points (-1, -5) and (0, 1)

We know the y-intercept can be determined by setting x = 0 and solving for y.

From the graph, it is clear that

at x = 0, y = 1

Thus, the y-intercept = b = 1

We know the slope-intercept form of the line equation is

where m is the slope and b is the y-intercept

substituting m = 6 and b = 1 in the slope-intercept form

Therefore, the table represents the rule equation such as:

                                           Question # 8

Given the table

Input            Output

3                      -5

2                      -4

1                       -3

2                      -2

3                       -1

We know that relation is said to be a function from a set X to a set of Y if each element of x is related to exactly one element in Y.

In other words, there must not be repeated 'x' element, meaning the value of 'x' must be unique.

It is clear from the table that the value of x is unique and there is no repetition of x, meaning each element of x is related to exactly one element in Y.

Thus, the given table represents the function.

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
