You spend c dollars for
p identical pairs of pants. a friend claims that
because c increases if you increase p, and p
increases if you increase c, either corp could be
the independent variable. is your friend right or
wrong? explain.

Your friend is wrong.

Step-by-step explanation:

C is dependent upon the number of pairs of jeans purchased, making P independent.

Step-by-step explanation:

Given that we spend dollars for  p identical pairs of pants.

Let assume that the price of a pair of pants is 5$

So we can form an equation:

c = 5p

A friend claims that  because c increases if you increase p

It is true, in the above equation, p is the independent variable and c is dependent one. If we p increase in unit, c will follow up to increase 5$

p  increases if you increase c

It is wrong, only p can affect on c and only p is dependent variable.

So to sum up, the statement : either corp could be  the independent variable is wrong. Only one corp (p) is independent.

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
