Write the equation of the line that passes through the given points.
(0,−1) and (−3,−9)

Let's write the line in slope-intercept form.

y = mx + b

m = slope

b = y-intercept.

Let's use the two points to calculate our slope.

Slope = (-9 -(-1)) / -3 = -8 / -3 = 8 / 3

Our line so far: y = 8/3x + b

Let's plug one of our points into the equation to find b.

-1 = 8/3(0) + b

-1 = b

Our line is: y = 8/3x - 1

the median here is 25. your lowest value is 14 and highest value is 48. to find the third quartile, find the medium number in between 25 and 48 which would be 42 i believe.
