Determine graphically whether each given point is a solution to the system of linear equations.

y = 4x-9
y = -2x+3
(2, -1)

Is there any good online graph which could help me plot the points and stuff?

• MATH -

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.
