Answer:

$slope = \frac{(y _{2} - y _{1})}{(x _{2} - x _{1})} \\ = \frac{(9 - 2)}{(9 - 0)} \\ = \frac{7}{9} \\ hence \: slope \: is \: \frac{7}{9}$

Jimmie graphs a quadratic function and finds that its zeros are at x=2 and x=3. Which function could Jimmie have graphed?

HACTEHA [7]

The function Jammie graphed is $x^2-5x+6=0$

Step-by-step explanation:

The zeros of quadratic function are at x=2 and x=3

We can write them as:

$x-2=0\,\,and\,\,x-3=0\\or\\(x-2)(x-3)=0$

Multiplying them

$(x-2)(x-3)=0\\x(x-3)-2(x-3)=0\\x^2-3x-2x+6=0\\x^2-5x+6=0$

So, The function Jammie graphed is $x^2-5x+6=0$

The point of intersection of the lines has an e-coordinate of?

34kurt

Use the substitution method
use the first equation, let y = k - x
plug y = k - x into the second equation
==> 2x + 3(k - x) = k + 1
==> 2x + 3k - 3x = k + 1
==> -x = k - 3k + 1
==> -x = -2k + 1
==> x = 2k - 1 is the answer
