Use the graph to write a linear function that relates y to x

The equation of a line can be predicted easily if two points are given. Thus, the equation of the required line is .

We need to determine the equation of the line with the help of the given graph.

Now, take two points from the graph. The points are ( 1, 4 ) and ( 2, 4 ).

The if a line passed through the two points say , then the equation of the line can be formulated as:

Therefore, apply the formula and solve it further.

Thus, the equation of the line is

y = 3

Step-by-step explanation:

This is a constant function

y = 3

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)

(a + b) (a^2 - a b + b^2)
