What is the equation of the line that passes through the point(-8,1) and has a slope of -3/4

vodka [1.7K]

Answer:

slope = -3/4

using the formula

y -y1 = m(x -x1)

y -1 = -3/4(x -(-8))

y -1 = -3/4(x +8)

cross multiply

4(y -1) = -3(x +8)

4y -4 = -3x -24

4y = -3x -24 +4

4y = -3x -20

divide both sides by 4

y = -3/4 x -5 (equation of the line)

horrorfan [7]

Answer:

Option A) Combined, with a saving of x-y cents

Step-by-step explanation:

We are given the following in the question:

The rate to mail a package is x cents for first pound and y cents for each additional pound.

$x>y$

Weights of packages =

3 pounds and 5 pounds

Cost of combined package:

Total weight = 8 pounds

$C\text{(combined)} = x + 7y$

Cost of sending separately:

$C\text{(separated)} = (x + 2y) + (x + 4y) = 2x + 6y$

Difference between cost of sending the packages separately and combined

$C\text{(separated)}-C\text{(combined)} \\=2x + 6y-(x+7y)\\=(x-y)\text{ cents}$

Thus, sending the packages combined is a cheaper method with a saving of (x-y) cents

Thus, the correct answer is:

Option A) Combined, with a saving of (x-y) cents
