Which sentences describe the relationship between an expression and an equation? select all that apply. an equation contains variables; an expression never does. an equation contains an equal sign; an expression does not. both expressions and equations contain numbers and/or variables. an expression has addition and subtraction; an equation never does. an expression involves multiplication, but equations only use addition.

B and C

Step-by-step explanation:

Equation:

It contains variables , signs , and equal sign

for example:

x+3=y-9

Expression:

It does not contain equal sign everything else is same

now, we will verify each option

option-A:

An equation contains variables; an expression never does

expression can also contain variables

so, this is FALSE

option-B:

An equation contains an equal sign; an expression does not

So, this is TRUE

option-C:

Both expressions and equations contain numbers and/or variables

so, this is TRUE

option-D:

An expression has addition and subtraction; an equation never does

Equation can have subtraction and addition sign as well

so, this is FALSE

option-E:

An expression involves multiplication, but equations only use addition

Both can have multiplication and addition

so, this is FALSE

Step-by-step explanation:

slope of -2 means the slope is -2/1

from (3, - 8) you can find the y intercept by going backwords until x = 0

(2,-6)

(1,-4)

(0,-2)

so the y intercept is -2

y = -2x - 2
