What is the slope of the line and what is the solution and what does it mean in this situation

The slope of a line refers to the steepness of a line. It can be modeled using the following formula.

m(slope) = (y2 - y1)/(x2 - x1)

In which two ordered pairs on the line would be (x1, y1) and (x2, y2).

A solution of any line is an ordered pair that sits on the line. So for instance, if we had the line below:

y = 2x - 1

And we had the x-value of -1, then we would put that into the equation to find the y-value.

y = 2(-1) - 1

y = -2 - 1

y = -3

Then we would have a solution using that ordered pair (-1, -3)

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
