Slope 11: Point-Slope Form

Use the point slope formto write an equation of a line which passes through (2, 7 ) and has the slope; m = -4 y - 7 = - 4(x - 2)y + 7 = - 4(x - 2)y - 7 = - 4(x + 2)y - 2 = - 4(x - 7)Use the point slope formto write an equation of a line which passes through (-3, 8 ) and has the slope; m = 2/3y - 8 = 2/3 (x + 3)y + 8 = 2/3 (x - 3)y - 3 = 2/3 (x - 8)y + 3 = 2/3 (x + 8)Use the point slope formto write an equation of a line which passes through (-2, -7 ) and has the slope; m = -9 y - 7 = - 9 (x - 2)y - 2 = - 9 (x - 7)y + 7 = - 9 (x + 2)y + 2 = - 9 (x + 7)Write the point-slope form equation of the line as described below. through: (- 9, 2), slope = − 3/4y + 2 = - 3/4 (x - 9)y - 9 = - 3/4 (x + 2)y + 9 = - 3/4 (x - 2)y - 2 = - 3/4 (x + 9)Write the slope of the line that passesthrough the following points. (1, −19), (−2, −7) y + 7 = 4 (x + 2) y + 19 = 4 (x - 1)y + 7 = - 4 (x + 2)y - 19 = - 4 (x - 1)Write the slope of the line that passesthrough the following points. (20, 8), (9, 16) y - 16 = 8/11 (x -9)y - 8 = - 11/8 (x - 20)y - 16 = - 8/11 (x - 9)y - 9 = 8/11 (x - 16) Write the slope of the line that passesthrough the following points. (6, −12), (15, −3)y - 6 = 1 (x + 12)y + 12 = - 1 (x - 6)y + 3 = x - 15y + 3 = - 1 (x - 15) |
