Determine graphically whether each given point is a solution to the system of linear equations.
y = 4x9
y = 2x+3
(2, 1)
Is there any good online graph which could help me plot the points and stuff?

Henry,
Graph the 2 Eqs, and the point of intersection should be (2, 1).
Use the given points for graphing.
Eq1: Y = 4X  9. (1,5), (3,3),(4,7).
Eq2: Y = 2X + 3. (0,3),(3,3), (4,5).
Straight lines are easy to graph; so
no special equipment is required.
