aisha and carolina each sketch a graph of the linear equation y = -x +
uses the equation y =
x + 2 to sketch the graph, and carolina uses the
equation y=-
a. explain how this leads them to use different steps to construct their graphs.
b. will the two graphs look the same? explain

Evaluate the discriminant of each equation. tell how many solutions each equation has and whether the solutions are real or imaginary. x^2 - 4x - 5 = 0
