Write an equation in slope - intercept form for the line that satisfies each set of conditions. answers only 24. slope 0.25, pas
ses through (0,4) 26. slope 3/2, passes through (-5,1) 28. slope 4, passes through the origin 30. passes through (7,1) and (7,8) 32. passes through (-2,-3) and (0,0) 34. x- intercept = 1/3, y- intercept = -1/4
24.) y = mx + b slope(m) = 0.25 (0,4)...x = 0 and y = 4 now we sub and find b, the y int 4 = 0.25(0) + b 4 = b so ur equation is : y = 0.25x + 4
26.) y = mx + b slope(m) = 3/2 (-5,1)....x = -5 and y = 1 sub and find b, the y int 1 = 3/2(-5) + b 1 = - 15/2 + b 1 + 15/2 = b 2/2 + 15/2 = b 17/2 = b ur equation is : y = 3/2x + 17/2
28.) y = mx + b slope(m) = 4 (0,0)...x = 0 and y = 0 time to sub 0 - 4(0) + b 0 = b so ur equation is : y = 4x + 0.....or just y = 4x
30.) (7,1)(7,8)....notice how the x's are the exact same number....this means that ur line is a vertical line with a slope that is undefined. ur equation is : x = 7
