Write an equation in standard form for a line passing through the pair of points

Given the box plot, will the mean or the median provide a better description of the center? box plot with min at 10.5, q1 at 11.5, median at 12.5, q3 at 13.5, max at 15

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

Rewrite the following quadratic functions in intercept or factored form. show your work. f(x) = 3x^2 - 12
