- Solving systems of equations using graphing
Step-by-step explanation:
<u>Step 1: Define system</u>
y = x + 1
y = -1/2x + 4
<u>Step 2: Identify Solution</u>
The solution to the systems of equations when graphed will be where the 2 lines intersect. According to the graph, the 2 lines intersect at (2, 3).
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form: (-1,0)
Equation form: x=-1,y=0
