Describe the line whose equation is   – x – y = 9

All of the following statements pertaining to adding or subtracting polynomials are true except:

Consider the equation V = lwh.  What inverse operation would you use to solve for w?

Simplify -4(a – 5) – 6(2 + a).

Which of these ordered pairs are points on the graph of y = 3x – 6?

If the equation y = x + b represents a line that passes through the point (5, -3), determine the value of the y-intercept.

Which graph represents the graph of the relation 5x – 2y = 0? Hint: Try estimating an (x , y) point off each line and subbing into the given formula to help determine which graph best represents this relation.

Simplify (5×2 – 3xy + 9y2) – (-4×2 + 2xy + 3y2).

Simplify -x(-7×2 – 3x + 5) – 2x(x2 + 6x – 10).
