Question 1 Report

A student told to draw the graph of y = x² + 4x - 6. He is then told to draw a liner graph on the same axis such that the intersection of the two graphs will give the solutions to the equation x² + 4x - 7 = 0, What is the equation of the linear graph he needs to draw?

x = 1

x = -1

y = 1

y = -1

x + y = 1
