they found a nursery that charges a packaging fee of $3.00 plus $9.00 per pound for grass seed.

which of the following linear equations shows grass seed at $9.00 per pound?

y=9x+3

Step-by-step explanation:

$9 PER Pound, means that should be the slope of the equation.

Plus the base fee of another 3 dollars, your equation should be y=9x+3.

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
