Two or more equations that define a relationship between variables are called a of equations.

Two or more equations that define a relationship between variables are called a system of equations.

We know that a system of equations are the collection of two or more equations which determine a relationship between the variables i.e. the unknown terms.

The system of linear equations in terms of two variables x and y is given by:

  ax+by=c

and  a'x+b'y=c'

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

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.
