A. the  x- and  y-coordinates of two points on the line B. the slope of the line C. the x-coordinates of two points on the line D. the y-coordinates of two points on the line Hint 2. State the slope and the coordinates of a point on the graph of the equation y – 6 = –3(x + 1). A. m = –3; (–1, 6) B. m = –3; (6, –1) C. m = –3; (1, –6) D. m = ; (-1, 6) Hint 3. Consider the graph below. In 1990, the population of Iowa Falls, Iowa, was 5435. In 1998, the population was 5137. An equation in point–slope form for the population of Iowa Falls, as shown in the graph, is______. A. B. C. D. Hint 4. Write the point–slope form of an equation for the line passing through (2, 3) with slope 2. A. y + 3 = 2(x + 2) B. y + 2 = 2(x + 3) C. y + 2 = 2(x + 3) D. y – 3 = 2(x – 2) Hint 5.
