What is the first step in evaluating the expression shown below? (12.9-3.1) 6.2 - 2 + 43
A. Multiply 3.1 and 6.2.
B. Add 2 and 43
C. Subtract 3.1 from 12.9.
D. Subtract 2 from 6.2.

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
