1. Write an equation in point-slope form of a line having slope as ¾ and contains the point (5, –2).
2. Write an equation in point-slope form of a line having slope as 3 and contains the point (–2, 7).
3. Write an equation in slope-intercept form of a line having slope as –3 and contains the point (0, 2.5).
4. Write an equation in slope-intercept form of a line having slope as –½ and contains the point (4, –6).
5. Write an equation in slope-intercept form of a line passing through (1, 5) and (3, 11).
Plan For line PQ to be parallel to MN, the alternate exterior angles must be congruent. So, m WXP = m ZYN. Substitute the given angle measures into this equation and solve for x. Once you know the value of x, use substitution to find m ZYN.
Examine Verify the angle measure by using the value of x to find m WXP. That is, 11x – 25 = 11(15) – 25 or 140. Since m WXP = m ZYN, m WXP m ZYN and || .
