Question
The pair of equation x = a and y = b graphically
representing lines which areSolution
The equations x = a and y = b represent: x = a is a vertical line passing through (a,0). y = b is a horizontal line passing through (0,b). These two lines are perpendicular to each other and intersect at the point (a,b). The given pair of equations graphically represents two perpendicular lines that intersect at (a, b).
