Answer:
The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.
Step-by-step explanation:
2 = degree
x = variable
expression = <span>3x^2-4x+1
coefficients = 3 and -4
constant = 1</span>
