Write an equation of the line that passes through the given point and is parallel to the given line.
40. (4,1); y=-2x+7 41. (0,6); y=5x-3 42. (-5,-2); y=2/3x+1
answer: 2.95% decrease
first, find the unit price of the original cereal and the new cereal. then use those values to find the percent change.
the z-score = (x - m) / d where m = the mean, d = the standard deviation and x is the individual score.
chris: z-score = (185.13 - 185.52) / 0.327
karen: z-score = (110.13 - 110.3) / 0.106
take out the common factor (3x + 7)
6x(3x + 7) + 5(3x + 7) = (3x + 7)(6x + 5) ← in factored form
rewrite the equation in slope-intercept form by isolation the y value:
3y = 2x - 3
to isolate y divide all terms by 3:
y = 2x/3 - 3/3
y = 2/3x -1
the slope is the value with x
slope = 2/3
