What we need to memorize when finding the slope is this formula:

\displaystyle \large{m =  \frac{y_2 - y_1}{x_2 - x_1} }

m here represents the slope. I hope this does not confuse you with <em>l</em><em>i</em><em>n</em><em>e</em><em> </em><em>m</em><em>.</em>

The problem here is that we do not have any given points, but we have a way.

If we notice on the graph, the graph contains or passes through (2,-1) and (-2,1). We can use these points to find the slope. So let these be the following:

\displaystyle \large{(x_1,y_1) = (2 ,- 1)} \\  \displaystyle \large{(x_2,y_2) = ( - 2 ,1)}

Then we substitute these points in the formula.

\displaystyle \large{m =  \frac{  1 - ( - 1)}{ - 2 - 2} }

negative × negative = positive.

\displaystyle \large{m =  \frac{  1  + 1}{ - 2 - 2} } \\  \displaystyle \large{m =  \frac{  2}{ - 4} } \longrightarrow \boxed{m =  -  \frac{1}{2} }

Since m represents the slope. Therefore, the slope of line m is -1/2

If f(x) varies directly with x2, and f(x) = 96 when x = 4, find the value of f(2).
Scilla [17]
F ( x ) = k * x²
f ( 4 ) = 96
96 = k * 4²
96 = 16 k
k = 96 : 16
k = 6
f ( 2 ) = 6 * 2² = 6 * 4 = 24

What to do if quadratic equation has a negative spuare root?
alex41 [277]

If the negative square root is found to be one of your solutions, then that is indicative of a pair of imaginary roots (the imaginary i). According to the conjugate rule, if you have one solution that is imaginary, you will have another but with the opposite sign. For example, if a solution to a quadratic is found to be 2 - i, then its conjugate, 2 + i is also a solution. They will ALWAYS go in pairs. Same thing with radical solutions. If one solution is found to be 3+\sqrt{5}

then 3-\sqrt{5} will also be a solution.
