Write in simple radical form:

WARRIOR [948]

Answer:

The answer to your question is $\frac{2}{3}$

Step-by-step explanation:

Here, there is a difference of squares, so just solve it and simplify

$( 1 + \frac{1}{\sqrt{3} } ) (1 - \frac{1}{\sqrt{3} } )$

Multiply the binomials

= 1 - $\frac{1}{3}$

Simplify

= $\frac{3 - 1}{3}$

= $\frac{2}{3}$

the point slope form of the equation of a line that passes through (8,4) and (0,2) is y-4=1/4(×-8) what is the slope intercept f

marissa [1.9K]

Answer:

$\large\boxed{y=\dfrac{1}{4}x+2}$

Step-by-step explanation:

The slope-intercept form of the equation of a line:

$y=mx+b$

m - slope

b - y-intercept → (0, b)

The point-slope form of the equation of a line:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point

We have the equation of a line:

$y-4=\dfrac{1}{4}(x-8)\to m=\dfrac{1}{4}$

and the point (0, 2) → b = 2.

Substitute:

$y=\dfrac{1}{4}x+2$
