If a system of linear equations has the unique solution (2, −3), then its graph consists of what? a. parallel lines b. lines that intersect at a single point c. identical lines d. a y-intercept at -3

Let's assume that the solution written correctly is:
 (2, -3)
 A linear system of equations contains a single solution when the lines intersect at a point.
 In this case, the ordered pair or intersection point is:
 (x, y) = (2, - 3)
 
 its graph consists of:
 B. Lines that intersect at a single point
