Answer:

y= -2x+9

Step-by-step explanation:

The equation will be written this way :

y= m*x+c

m is the slope
c is a constant
m =( f(4)-f(2))/(4-2)=(1-5)/2= -4/2 = -2
y = -2x+c
replace x and y by the coordinates of a point to get c
1= -2*4+c
c = 9

y = -2x+9

Answer:

y=-9/4.5+9

Step-by-step explanation:

To find the equation you do y=mx+b which means y= slope + y-intercept.

To get the slop you do rise over run which in this situation is 9/4.5. And the y-intercept is when the line touches the y-axis and in this problem it is 9. So the answer is y=-9/4.5+9

Solve.E6xplain how you get the answer without using a calculator 6/3 + 1/2

fiasKO [112]

I'm just gonna assume that 6/3 and 1/2 are fractions.

First you have to find common denominators for the fractions to be added.

The first common denominator divisible by both the denominators is 6.

So 2x3=6 and 1x3=3

and 3x2+6 and 6x2+12

so that would be 12/6 + 3/6

Then you would proceed to add both of the numerators together which are 12 and 3.

To get a total of 15/6. You can also simplify that into a mixed number 2 1/2.

Which statement about the polynomial function g(x) is true?

yKpoI14uk [10]

When leading coefficient is 1 , the root will be an integer for g(x) = 0

Option 4 is the right answer.

<h3>What is a Polynomial Function ?</h3>

Functions of independent variable in which the variable can appear more than once with different powers.

$\rm g(x) = a_n x^n + a_{n-1}x^{n-1} + ................+ a_o$

Let this represents the polynomial function

where $\rm a_n \; is\;the \;leading \; coefficient \; a_o \; is \;the\;last \;term$

Then the according to rational root theorem ,

The root of the function is given by

$\rm \dfrac{p}{q} = \dfrac{factor \;of\; the\; last\; term}{factor \;of \;the\; leading coefficient}$

So when leading coefficient is 1 , the root will be an integer for g(x) = 0

Option 4 is the right answer.
