Question 58786
You forgot the commas in the coordinates so I'm taking a guess, you should get the idea:  
Complete the ordered pairs for the equation y = 8x + 16.
(0, ),(7/8, ),( ,0),(-7/8, )
For (x,y)=(0, )	let x=0 and solve for y:
y=8(0)+16
y=0+16
y=16  (0,16)
:
For (x,y)=(7/8, ) let x=7/8 and solve for y
y=8(7/8)+16
y=7+16
y=23 (7/8,23)
:
For (x,y)=( ,0) let y=0 and solve for x
0=8x+16
-16=8x+16-16
-16=8x
-16/8=8x/8
-2=x  (-2,0)
:
For (x,y)=(-7/8, ) let x=-7/8 and solve for y
y=8(-7/8)+16
y=-7+16
y=9  (-7/8,9)
Happy Calculating!!!
