General Linear Form

Problem : Write an equation of the following line in point-slope form:

y - 2 = (x + 1)
Note: Other solutions are possible.

Problem : Write an equation of the line which passes through (2, 3) and (7, - 2) .

y - 3 = - (x - 2) or y + 2 = - (x - 7)
Note: Other solutions with m = - 1 are possible.

Problem : Write an equation of the line which passes through (- 3, - 7) and has slope m = .

y + 7 = (x + 3)

Problem : Write an equation of the line which passes through (4, 6) and is parallel to the line y = - x + 1 .

y - 6 = - (x - 4)

Problem : Write an equation of the line which passes through (5, - 2) and is parallel to the line which passes through (3, 5) and (5, - 3) .

y + 2 = - 4(x - 5)

Problem : Write an equation of the line which passes through (- 1, 4) and is perpendicular to the line y = - x - 19 .

y - 4 = (x + 1)

Problem : Write an equation of the line which passes through (- 3, - 3) and is perpendicular to the line 7y - 8x = 0

y + 3 = - (x + 3)

Problem : Graph y - 4 = - (x + 5)

y - 4 = - (x + 5)
