Oneta writes an algebraic a spression with 3 terms. the y-term has a coefficient of negative 3 and the x-term has a coefficient of one. the expression does not have a constant term which expression could she have written.

Option a. x - y^2 - 3y

Step-by-step explanation:

The options of the questions are

a. x - y^2 - 3y

b. x - 3y + 6

c. x + 3y^2 + 3y

d. x + 3y + 7

we know that

The expression has 3 terms

The y-term has a coefficient of negative 3 and the x-term has a coefficient of one

The expression does not have a constant term

Verify each case

case a) we have x - y^2 - 3y

The expression has 3 terms > is ok

The y-term has a coefficient of negative 3 ---> is ok

The x-term has a coefficient of one > is ok

The expression does not have a constant term > is ok

therefore

She could have written this expression

case b) we have x - 3y + 6

The expression has 3 terms > is ok

The y-term has a coefficient of negative 3 ---> is ok

The x-term has a coefficient of one > is ok

The expression does not have a constant term ---> is not ok (the expression have a constant term of 6)

therefore

She couldn't have written this expression

case c) we have x + 3y^2 + 3y

The expression has 3 terms > is ok

The y-term has a coefficient of negative 3 ---> is not ok (the y-term has a coefficient of positive 3)

therefore

She couldn't have written this expression

case d) we have x + 3y + 7

The expression has 3 terms > is ok

The y-term has a coefficient of negative 3 ---> is not ok (the y-term has a coefficient of positive 3)

therefore

She couldn't have written this expression

step-by-step explanation:

no of data

divide by no of mode

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
