find the slope of the line that passes through th epoints (1,4)and(-1,6)
i have to the same way in this problem liek they did in that example?
Find the slope of the line that passes through the points (-3,5) and (-5,-8).
First find the slope: m = y1 - y2 / x1 - x2
m = 5 - (-8) 13
----------- =---- = 6.5
-3 - (-5) 2
Using either point: (-3,5)
Remember the form: y - y1 = m ( x - x1)
Substitute: y - 5 = 6.5 ( x - (-3))
y - 5 = 6.5 (x + 3) Ans.

solve by completing the square:
3x^2 + x = -5
subtract x form both sides...
