a million. (y2 – y1)/(x2 – x1) = (-9 - 4)/(-5 - -6) = -thirteen/ a million = -thirteen 2. (y2 – y1)/(x2 – x1) = (2 - -7)/(6 - 6) = 9/0 = undefined 3. (y2 – y1)/(x2 – x1) = (a million - -3)/(-2 - 7) = 4/-9 = -4/9 4. y = 8 y = 0x + 8 slope = 0.5. 2x - 3y = sixteen 2x -sixteen = 3y 3y = 2x - sixteen y = 2/3 x - sixteen/3 slope = 2/3 6.a) 3x - 4y = 7 3x - 7 = 4y 4y = 3x - 7 y = 3/4 x - 7/4 and 8x + 6y = 7 6y = -8x + 7 y = -8/6 x + 7/6 y = -4/3 x + 7/6 because of the fact the slopes are 3/4 and -4/3 (they're damaging inverses of the different) the strains are perpendicular. b) y = 4x - 3 and 16x + 4y = 7 4y = -16x + 7 y = -4x + 7 those strains are neither parallel or perpendicular because of the fact to be parallel the slopes could desire to be equivalent or to be perpendicular they could desire to be damaging inverses. they're neither. 7. y = mx + b b is the y-intercept, that's given because of the fact the element. y = 0x + a million y = a million 8. a) y - y1 = m(x - x1) y - 5 = -3(x - 5) y - 5 = -3x + 15 y = -3x + 15 + 5 y = -3x + 20 b) (0, 6); m = 3/2 y = mx + b (comparable as 7) y = 3/2 x + 6 9. First locate slope. m = (y2 - y1)/(x2 - x1) = (-10 - -8)/(-6 - -6) = -2/0
