    1. Ture or false: The ordered pair (-1, 4) is a solution to the linear inequality:
    -5x + 2y < = 13

    2. We know that y varies directly with x, and y = 1.5 when x = 0.3. Write the linear equation relating the two variables in slope-intercept form.

    3. choose the graph of the function f(x) = x^2 - 8x + 16

    1. We can substitute -1 for x and 4 for y to the left-hand side of the inequality, which gives:
    -5x + 2y = -5 * (-1) + 2 * 4 = 5 + 8 = ...
