We can use completing the square.We add 16 and subtract 7 to both sides. Now we get m^2+8m+16=9. The left sides becomes (m+4)^2=9. Taking the square root of both sides and subtracting 4 we get -1 and -7.

A bottle of water costs $1.50. Explain how you would make a graph of four ordered pairs to model the total cost of the water in
Vanyuwa [196]
Total cost = 1.50 per bottle
y = 1.50x
If x = 1, y = $ 1.50 (1,1.5)
If x = 2, y = $ 3.00 (2,3)
If x = 3, y = $ 4.50 (3, 4.5)
If x = 4, y = $ 6.00 (4, 6)
There are your 4 sets of ordered pairs to graph.
You could continue with more x-values to get more ordered pairs.
