Write the slopes intercept form of the equation of the line through the given points.

Anika [276]

Slope intercept form
y=mx+b
m=slope
b=yintercept

slope for the line passing through the points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)

given
(2,-2) and (2,-3)
slope=(-3-(-2))/(2-2)=(-1)/0=undefined

y=undefinedx
this means that the equation is x=something
we see
(x,y)
(2,-2)
(2,-3)
x=2 is the equation
we cannot write it in slope intercept form

X^2-x+2=0 Please use the quadratic formula

Ainat [17]

Answer:

$\boxed{\sf x=\cfrac{1\pm \sqrt{-7} }{2}}$

Step-by-step explanation:

$\sf x^2-x+2=0$

Use quadratic formula:

$\boxed{\sf \frac{-b\pm \sqrt{b^2-4ac}}{2a}}$

$\sf a=1, b=-1, c=2$

___________________________

$\sf x_1,_2=\cfrac{-\left(-1\right)\pm \sqrt{\left(-1\right)^2-4\times \:1\times \:2}}{2\times \:1}$

$\sf \sqrt{\left(-1\right)^2-4\times \:1\times \:2}$

$\sf =\sqrt{-7}$

_________________

$\sf x_1,_2\cfrac{-\left(-1\right)\pm \sqrt{-7}}{2\times \:1}$

$\sf -(-1)=1$

$2\times 1=2$

$\sf x_1,_2=\cfrac{1\pm \sqrt{-7} }{2}$
