The pricing of the boxes seems to be consistently 2.40 per box. Ethan's cost is
.. 52.80 = 2.40 * (# of boxes)
.. 52.80/2.40 = (# of boxes)
.. 22 = # of boxes
Ethan has bought 22 boxes for 52.80.
Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (1, 2) and (x₂, y₂ ) = (1, - 3)
m =
= 
Since division by zero is undefined then the slope of the line is undefined
Answer:

Step-by-step explanation:
The point-slope form of an equation of a line:

m - slope
Parallel lines have the same slope.
We have the equation in the slope-intercept form (y = mx + b)

Put to the point-slope equation value of the slope and the coordinates of the point (4, -5):

23.4 ft2
