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.
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?
