3.)
y = -2x + 8
y = x - 1
Explain how you will solve the pair of equations by SUBSTITUTION. Show ALL the steps and write the solution in (x,y) form

Answer 1

As we have learned when given a pair of equations, we must always find a Point of Intersection....or, in other words...the solution of the lines given to us. As we know there can be one solution, in this case we view the graph; see where they intersect, and realize that the solution to these lines Point of Intersectio) is at (4,4).
