An y table shows the following coordinate pairs: five comma twenty-five, one comma one, and three comma nine.
Lance bought 3 CDs and spent twenty-seven dollars. Jacob bought 5 CDs and spent forty-five dollars.
y equals x minus thirteen
A graph shows a line connecting the points: negative seven comma three and five comma negative four.

Answer 1

Do you know the difference between a linear, non-linear and direct variation system of equations?

Answer 2

yes

Answer 3

Explain each to me. :)

Answer 4

But just briefly. No paragraph answers.

Answer 5

linear keeps going in a line

Answer 6

Excellent.

Answer 7

Constant rate of increase.

Answer 8

non linear could because in form

Answer 9

Yup. Direct linear is all over the place, as my Alg. teacher would say :)

Answer 10

direct has pointes

Answer 11

When two variable quantities have a constant (unchanged) ratio, their relationship is called a direct variation. It is said that one variable "varies directly" as the other. The constant ratio is called the constant of variation.

Answer 12

Direct variation is in the form y=kx

Answer 13

^? 0.o

Answer 14

An y table shows the following coordinate pairs: five comma twenty-five, one comma one, and three comma nine.
Lance bought 3 CDs and spent twenty-seven dollars. Jacob bought 5 CDs and spent forty-five dollars.
y equals x minus thirteen
A graph shows a line connecting the points: negative seven comma three and five comma negative four

Answer 15

A) An y table shows the following coordinate pairs: five comma twenty-five, one comma one, and three comma nine.
y= 5, 25, 1, 3, 9.
Lance bought 3 CDs and spent twenty-seven dollars. Jacob bought 5 CDs and spent forty-five dollars.; Soo, 3 CDs, $27.00 5 CDs, $45.00
y equals x minus thirteen ; y=x-13
A graph shows a line connecting the points: negative seven comma three and five comma negative four ; So I line of ; -7, -3, -5, -4..
