How do you find the axis of symmetry if only given points (-5,-1) and and (3, -1)?
Plot the points on graph paper and notice that you have the same y-coordinate for both points.
This is a parabola that either opens upward or downward because at
Because a parabola is symmetric, the axis of symmetry must lie exactly midway between the two x-values.
