### The Graph Method

Step 1

Graph both equations

Step 2

On the right, the **graph** of the two lines

The solution of the system is the point of intersection : (1,2)

**Practice** Problems

Step 1

Step 2

Step 1 is to Graph both equations

The solution of this system is the point of intersection : (1,3).

Step 1

Rewrite each equation in slope intercept form

$$ \text{ A) } 2y = 4x + 2 \\ \frac{1}{2} 2y = \frac{1}{2}(4x+2) \\ y = 2x +1 $$

$$ \text{ B) } 2y = 8x - 2 \\ \frac{1}{2} 2y = \frac{1}{2}( 8x - 2) \\ y = 4x +1 $$

This system of lines is the same system that we looked at in the last example.

Step 2

Graph each equation to find the point of intersection --which is the solution. (same as earlier problem)
