HELP PLEASE Which of these describes the equation-18x + 9y = -416

A: this equation is not linear because it has 2 variables not 1.

B: The equation is not linear because it is not in the form y = mx + b.

C: the equation is linear because it has variables with exponents of 0.

D: The equation is linear because it can be rewritten in the form y= mx + b.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,

mrb

yes

step-by-step explanation:

yes

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
