1. Find the point of intersection by graphing both lines and observing where they intersect.
Y = -4x + 2
Y = x - 3
2. Find the point of intersection by graphing both lines and observing where they intersect.
Y = ½ x - 4
Y = -½ x - 1
3. Tell whether the ordered pair is a solution of the equation. Just substitute the given x and y to see if the equation “works”. Write “solution” if it works and “not solution” if it doesn’t.
a. y=4x + 2; (2,10)
b. 2x + y = 5; (7, 5)
4. Set up a table of values:
Y(1) = 1/2x + 5
Y(2) = -2x -1
x y(1)
1/2x+5 y(2)
-2x - 1 (x,y(1))
(x, y(2))

5. Graph the linear equations using a table of values.
y(1) =1/3x - 3
y(2) = 1/3x + 1
1. The point of intersection is (1, -2).
2. The point of intersection is (-2, -2).
3.
a. (2, 10) is a solution of the equation y = 4x + 2.
b. (7, 5) is not a solution of the equation 2x + y = 5.
