[QUOTE="Jacob, post: 2629746, member: 219323"] 1. A line passes through (2, –1) and (8, 4). a. Write an equation for the line in point-slope form. b. Rewrite the equation in standard form using integers. (1 point) y + 1 = 5/6(x – 2); –5x + 6y = –16 y – 1 = 5/6(x – 2); –5x + 6y = 16 y + 1 = 5/6(x + 2); –5x + 6y = –16 y – 2 = 5/6(x + 1); –5x + 6y = 17 2.
