y = -2x + 5 [substitute the given value of one variable and solve for the other variable.
.
(0, ), ( , 5), ( 3/2, ), ( ,1)[Ordered pairs are always (x,y)]
y = -2x + 5 (0,y)
y=-2(0)+5 [plug in the value for "x" and solve for y]
y=5
Ordered pair is (0, 5)
.
y = -2x + 5 (x, 5))
5=-2x+5 [plug in the value for "y" and solve for x]
5-5=-2x+5-5
0=-2x
0/-2=-2x/-2
0=x
Ordered pair = (0,5)
.
y = -2x + 5 (3/2,y)
y=-2(3/2)+5 [plug in the value for "x" and solve for y]
y=-6/2+5
y=-3+5
y=2
Ordered pair is (3/2, 2)
.
y = -2x + 5 (x, 1)
1=-2x+5 [plug in the value for "y" and solve for x]
1-5=-2x+5-5
-4=-2x
-4/-2=-2x/-2
2=x
Ordered pair is (2, 1)
