Wayne is solving the linear system of equations using the graphical method, but it can also be solved analytically.
We will solve the system of equations analytically to find in which point Wayne will find the solution graphically.
Resolving we have:
y = -34x + 5 (Eq1)
x = -2 (Eq2)
Substituting (Eq2) in (Eq1) we have
y = -34 * (- 2) + 5
y = 73
Therefore the point will be
(x, y) = (- 2,73)
answer
the point will have found the solution of this system of linear equations is (-2,73)
Step-by-step explanation:
thr standard form for a quadratic equation is:
ax²+bx+c
in this example, a=1, b=(-1), c=(-42)
