User: Re-write this equation in the standard form. y - 3 = 2.5(x + 1) a. 5x + 2y = -11 c. 5x - 2y = 11 b. 5x - 2y = -11 d. 5x + 3y = 22

Weegy: y - 3 = 2.5(x + 1); y - 3 = 2.5x + 2.5; y = 2.5x + 2.5 +3;; y = 2.5x + 5.5; Multiplying the above equation by 2; 2y = 5x + 11; 5x - 2y + 11 = 0; 5x - 2y = -11;

If y = –48 when x = –8, find y when x = –3. a. y = 6x; –18 c. y = 6x; –21 b. y = 5x; –18 d. y = –6x; 18 User: y = 1/3x + 9 3x – 9y = 4 a. No, since the slopes are different. b. No, since the y-intercepts are different. c. Yes, since the slope are the same and the y-intercepts are the same. d. Yes, since the slope are the same and the y-intercepts are different.

The lines for y = 1/3x + 9 and 3x – 9y = 4 are parallel since the slope are the same and the y-intercepts are different.
