## Ex #1

Functions can be written as two-variable equations. Two-variable equations have INFINITE solutions. We can make a

__partial__list of these solutions in a table. We can then use the table to draw a graph of__all__of the solutions. Graph by completing the following table.__x | y__4 | 6 | | 1 | 0 Plot all four points on the provided graph and connect your points with a line.

## Ex #2

Graph 2x + 5y = 15 by completing the following table.

__x | y__0 | 2 | | 2 | 0 Plot all four points on the provided graph and connect your points with a line.Which of the following points is also on the line 2x + 5y = 15 ?

## Problem #1

Graph y = -2x + 1 by completing the following table.

__x | y__-4 | -2 | | -3 | -7 Plot all four points on the provided graph and connect your points with a line. Hints: *to complete the 1st row, plug -4 in for x and__solve for y__---> y = -2(-4) + 1 *to complete the 2nd row, plug -2 in for x and__solve for y__---> y = -2(-2) + 1 *to complete the 3rd row, plug -3 in for y and__solve for x__---> -3 = -2x + 1 *to complete the 4th row, plug -7 in for y and__solve for x__---> -7 = -2x + 1Which of the following points is also on the line y = -2x + 1 ?

## Problem #2

Graph 5x - 4y = 20 by completing the following table.

__x | y__1 | 4 | | 2 | 5 Plot all four points on the provided graph and connect your points with a line. Hint: *to complete the 1st row, plug 1 in for x and__solve for y__---> 5(1) - 4y = 20 5 - 4y = 20 continue for each rowWhich of the following points is also on the line 5x - 4y = 20 ?
