Find the slope of the line given below by finding the rise and run. Also show or explain why the slope can be found from any two

mylen [45]

The slope of the line is
$\frac{3}{2}$
It can be found from any two points that fall on a line by using the formula
$y2 - y1 \\ - - - - \\ x2 - x1$
2 is x or y from the second point and 1 is x or y from the first point

For example in that problem the first point is -2,0 and the second one is 0,3

Solve the inequality: -1/4(x^2-4x+3)>0

Montano1993 [528]

Ok so assume that if you have
xy=0 then x and y=0
-1/4(x^2-4x+3)>0
multiply both sides by -4 to clear fraction (-4/-4=1)
flip sign
x^2-4x+3<0
factor
(x-3)(x-1)<0

we know that (+) times (-)=(-) and
(-) times (-)=(+) so we don't want them to be both negative, we want different sign
we cannnot have 3 since it would be (0)(2)<0 which is false
we cannot have 1 either since (-2)(0)<0 is also false
lets see if the solution is in betwen 3 and 1 or outside of 3 and 1
ltry 2
2^3-4(2)+3<0
8-8+3<0
3<0
false
therefor it is outside ie
x>3 and x<1
