What is the slope of the line passing through the points (2,-5) and(4,1)

pav-90 [236]

$\bf (\stackrel{x_1}{2}~,~\stackrel{y_1}{-5})\qquad (\stackrel{x_2}{4}~,~\stackrel{y_2}{1}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{1-(-5)}{4-2}\implies \cfrac{1+5}{2}\implies \cfrac{6}{2}\implies 3$

What are the solutions to this problem? (use the quadratic formula and i)<br><br> -2x^2+5x-11=0

Sever21 [200]

Step-by-step explanation:

The quadratic formula is:

$x = \frac{-b \pm\sqrt{b^2-4ac} }{2a}\\$

A, in this case, is -2.

B is 5

C is -11

x = $\frac{-5 \pm\sqrt{5^2-4(-2)(-11)} }{2(-2)}$

x = $\frac{-5\pm\sqrt{25 -88} }{-4}\\$

x = $\frac{-5\pm\sqrt{-63}}{-4}$

x = $\frac{-5+i\sqrt{63} }{-4}$ and $\frac{-5-i\sqrt{63} }{-4}$

We can break up the fraction to make it easier on our eyes

x = $\frac{5}{4}\pm\frac{i\sqrt{63} }{4}$

$\frac{\sqrt{63} }{4}$ ≈1.9843

x = $1.25 + 1.9843i\\1.25 - 1.9843i$
