1) Graph both equation and identify the
point of intersection.
y=2x+3
x+2y=8

Intersection Point: (0.4, 3.8)

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

Step 1: Define Systems

y = 2x + 3

x + 2y = 8

Step 2: Graph

Where the 2 lines intersect is the solution set to the systems of equations.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

thats not a system of equations, that is a solution
