Determine the slope of the line that passes through the points: x−8,0,4,5,y,−33,−1,15,19
Volgvan

Answer:

The equation of a line y = ax + b passes point (-8, -33) and point (0, -1) can be formulated by:

(Note: we do not need all of 4 points, 2 points are enough)

-33 = a x (-8) + b

  -1 = a x 0 + b

From 2nd equation, we have:

b = -1

From 1st equation, we have:

b - 8 x a = -33

=> -1 - 8 x a = -33

=> 8 x a = 32

=> a = 4

=>  The equation of line: y = 4a - 1

Hope this helps!

Natasha2012 [34]

Answer:

12 cups

Step-by-step explanation:

So we can just divide 9 by 3, which equals 3.

So we know 1/4 of the amount is 3 cups, so we can just do 3 x 4 which equals 12.  And this is the answer!

Hope this helps you!
