 Find an equation for the line with the given properties. Express the answer using the slope-intercept form of the equation of a line.
 Slope = 0; containing the point (-8, -1)
 Ans: y = 0x - 1
 -------------------------
 Find the real solutions of the equation by factoring.
 x^2 - 49 = 0
 Factor:
 (x-7)(x+7) = 0
 x = 7 or x = -7
 -------------------------------
 Write the expression in the standard form a + bi.
 (4 + 8i)(2 - 5i)
 = 4(2-5i) + 8i(2-5i)
 ---
 = 8-20i+16i-40i^2
 -----
 = (8+40) + (16-20)i
 -----
 = 48 - 4i
 -----------------
 Find the center (h, k) and radius r of the circle.
 x2 + (y + 4)2 = 36
 ----
 (x-0)^2 + (y-(-4))^2 = 36
 ----
 h = 0 ; k = -4 ; r = sqrt(36) = 6
