when you use all prime, non-one numbers for b and c, it cannot be factored most of the time
example
1x^2+7x+5
a=1
b=7
c=5
x=

What is the slope between the points (4,-1) and (-4,3)?
1 answer:
<em>The formula for slope is </em><em>.</em>
Subtract y1 from y2. (y1= -1, y2 = 3)
3 - -1 = 4
Now subtract x1 from x2. (x1 = 4, x2 = -4)
-4 -4 = -8
Divide the difference between the y coordinates by the difference between the x coordinates.
or 4 ÷ -8 = -0.5
<u>The slope between the two points is </u><u>-0.5</u><u>.</u>
Hope this helps love :)
