• Domain: {3, 4, 9}; Range: {0, 3, 5}
• Domain: {3, 4, 9, -1}; Range: {0, 3}
• Domain: {3, 4, 9, 5}; Range: {0, 3, 4}
• Domain: {3, 4, 9, -1}; Range: {0, 3, 4}

If f(x) = |x - 1| and g(x) = 5x - 2, then find f(-1) + g(0).

Determine whether y varies directly as x.

Assume that y varies directly as x. If y = 1/2 when x = 4, find the value of y when x = 10.

Write the equation of this line in slope intercept form: -y + 5 = -2x.

Write the equation of the line, in point-slope form, that contains these two points: (-4, 10) and (-6, 15).

• y - 15 = -3/2(x + 6)
• y - 10 = -5/2(x + 4)
• y - 10 = 2/5(x + 4)
• y - 10 = 5/2(x + 4)

Find the x- and y-intercepts of this line: 3y - x = -6.

• x-intercept: (0, 6), y-intercept: (-2, 0)
• x-intercept: (3, 0), y-intercept: (0, 3)
• x-intercept: (4, 0), y-intercept: (0, -4)
• x-intercept: (6, 0), y-intercept: (0, -2)

Write the equation of a line that is perpendicular to the line in question 2 and passes through the point (6, 0).
