COMPLETE THE ORDERED PAIRS FOR THE EQUATION Y=7X+21
( ,0),(2/7, ),(0, ),(-2/7, )
EACH BRACKET IS MISSING A NUMBER.
Remember that ordered pairs are in this order: (x,y)
For ( ,0) let y=0 and solve for x:
0=7x+21
0-21=7x+21-21
-21=7x
-21/7=7x/7
-3=x, the coordinate is: (-3,0)
For (2/7, ) let x=2/7 and solve for y
y=7(2/7)+21
y=14/7+21
y=2+21
y=23 The coordinate is (2/7,23)
For (0, ) let x=0 and solve for y
y=7(0)+21
y=0+21
y=21 The coordinate is: (0,21)
For (-2/7, ) let x=-2/7 and solve for y
y=7(-2/7)+21
y=-14/7+21
y=-2+21
y=19 The coordinate is (-2/7,19)
Happy Calculating!!!
