Write the equation of the line that passes through (4,8)and (4,6) write the equation in slope intercept form

Mathematics

Marianna [84]2 years ago

Answer:

x = 4

Step-by-step explanation:

If you were to plot the given points, you would quickly see that this is a vertical line where x = 4 (a visual is always a good place to start).  

Vertical lines have a slope that is undefined and are written in the form of x = .

If you had plugged into the slope formula m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} } , where (x_{1}, y_{1}) is (4, 8) and (x_{2}, y_{2}) is (4,6) the result would be as follows:

m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }

    = \frac{6 - 8}{4 - 4}

    = \frac{-2}{0}

Because you can not divide by 0, the slope is in fact undefined.

The slope that goes through the points (3,-4) and (-2,6)​
kicyunya [14]

Answer:

slope =  -2

Step-by-step explanation:

Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}

         = \frac{6-[-4]}{-2-3}\\\\= \frac{6+4}{-2-3}\\\\= \frac{10}{-5}\\\\= -2

If a polynomial function f(x) has roots -8, 1, and 6i, what must also be a root of f(x)?
Naddik [55]

Answer:

it must also have the root : - 6i

Step-by-step explanation:

If a polynomial is expressed with real coefficients (which must be the case if it is a function f(x) in the Real coordinate system), then if it has a complex root "a+bi", it must also have for root the conjugate of that complex root.

This is because in order to render a polynomial with Real coefficients, the binomial factor  (x - (a+bi)) originated using the complex root would be able to eliminate the imaginary unit, only when multiplied by the binomial factor generated by its conjugate: (x - (a-bi)). This is shown below:

(x-(a+bi))*(x-(a-bi))=\\(x-a-bi)*(x-a+bi)=\\([x-a]-bi)*([x-a]+bi)=\\(x-a)^2-(bi)^2=\\(x-a)^2-b^2(-1)=\\(x-a)^2+b^2

where the imaginary unit has disappeared, making the expression real.

So in our case, a+bi is -6i (real part a=0, and imaginary part b=-6)

Then, the conjugate of this root would be: +6i, giving us the other complex root that also may be present in the real polynomial we are dealing with.
