Remember the equation for slope is y=mx+b {m=slope, and b=y-intercept.} {Slope= rise/run}
1.) y= 2x+0
2.) y= -3/4x+0.5

P.S.: hope I helped :)

For both questions, all you really have to do is choose 2 exact points on each graph, and use those to find the slope. Thankfully, it already has 2 plots on there for us, so all we have to do is plug in the values in the equation below :)

Slope equation : y₂-y₁ / x₂-x₁

1)  (1,2), (-2,-4)

-4 -2 / -2 -2

-6 / -4

Simplify.

The slope of number one is 3/2

2) (-2,2), (6,-4)

-4 -2 / 6 + 2

-6 / 8

Simplify.

The slope for question 2 is -3/4

~Hope I helped!~

Factor the polynomial completely. Use synthetic division. <br><br> F(x) = x^3-7x-6
aleksklad [387]

Answer:

The factors of given polynomial    x =-1 , -2 and x =3

Step-by-step explanation:

<u><em>Step(i):</em></u>-

Given the polynomial  

                    f(x) =  x³ - 7x -6

 put x =-1

               f(-1) = (-1 )³- 7(-1) - 6 = -1+7-6=0

(x+1) is a one factor

By using synthetic division

                   x³    x²      x      constant

     x=-1  ↓   1      0      -7        -6

             <u>↓   0     -1      1          6</u>

            <u>       1       -1      -6       0     </u>

<u />

<em>The polynomial    x² - x - 6 </em>

<u><em>Step(ii):-</em></u>

The factors ( x+1)(x² - x - 6 ) = 0

     x = -1 and x² - x - 6 =0

    x =-1    and  x² - 3x + 2 x - 6 =0

   x =-1     and  x (x -3) + 2( x-3) =0

   x =-1     and  (x+2)(x-3) =0

<u><em>Final answer:-</em></u>

The factors of given polynomial    x =-1 , -2 and x =3
