2/17 R.R2.P1 Regents Review #2 Polynomials

The solution of an equation with two variables, x and y, is

• the set of all x values that make y = 0

• the set of all y values that make x = 0

• the set of all ordered pairs, (x,y), that make the equation true

• the set of all ordered pairs, (x,y), where the graph of the equation crosses the y-axis

Mrs. Rossano asked her students to explain why (3,−4) is a solution to 2y + 3x = 1. Three student responses are given below.

Andrea: “When the equation is graphed on a calculator, the point can be found within its table.”

Bill: “Substituting x = 3 and y = −4 into the equation makes it true.”

Christine: “The graph of the line passes through the point (3,−4).” Which students are correct?
