Plz i need help and plz explain

Montano1993 [528]

$\frac{ {x}^{2} - 7x + 12}{ {x}^{2} - x - 12 } \\ = \frac{ {x}^{2} - 4x - 3x + 12 }{ {x}^{2} - 4x + 3x - 12 } \\ = \frac{x(x - 4) - 3(x - 4)}{x(x - 4) + 3(x - 4)} \\ = \frac{(x - 3)(x - 4)}{(x + 3)(x - 4)} \\ = \frac{x - 3}{x + 3}$

x² - x - 12 ≠ 0

x² - 4x + 3x - 12 ≠ 0

x (x - 4) + 3 (x - 4) ≠ 0

(x + 3)(x - 4) ≠ 0

x ≠ -3 or x ≠ 4

Using graph paper, determine the line described by the given point and slope. Click to show the correct graph below.

gayaneshka [121]

When you know the coordinates of a point and the slope of a line, you can use the formula

$y-y_0=m(x-x_0)$

in your case, $(x_0,y_0)=(0,0)$ and $m=\frac{2}{3}$ , so you have

$y-0=\dfrac{2}{3}(x-0) \iff y=\dfrac{2}{3}x$
