What is the x - and y - intercepts of -3y = 7x - 21

x-intercept = (3,0); y-intercept = (0,7)

Step-by-step explanation:

-3y = 7x - 21

y = -7/3 x + 7 (divide both sides by -3)

y-intercept = (0,7) (y = mx + b; b is always y-intercept)

0= -7/3 x + 7 (plug in 0 for y to get x-intercept)

-7/3x = -7 (subtract 7 from both sides)

x = 3 (divide both sides by -7/3)

x-intercept = (3,0)

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
