# In Exercises 1–6, graph the given equations and determine how many solutions the system has, if any. 0.2 x − 0.1 y = 0.3 0.2 x + 0.2 y = 0.4

To determine

To graph: The system of equations consisting of 0.2x0.1y=0.3 and 0.2x+0.2y=0.4. Also, determine the number of solutions the system has, if any.

Explanation

Given Information:

The system of equations is;

0.2xā0.1y=0.30.2x+0.2y=0.4

Graph:

Consider the equations,

0.2xā0.1y=0.30.2x+0.2y=0.4

Rewrite the given equations by isolating y,

y=2xā3y=āx+2

Use the graphing calculator to determine the solution of the given system of equation,

Step 1: In the TI-83 calculator press the ON key.

Step 2: Click on the Y= button
