Using cross multiplication

$x^{2} -2x-8 =0$
(x-4)(x+2)=0
x-4=0
x+2=0

Thus x=4,-2

1 point<br> What is the slope of a line perpendicular to 3x + 4y = -2?

Nady [450]

Answer:

4/3

Step-by-step explanation:

In slope-intercept form $y=mx+b$ , $m$ represents the slope of the line.

Let's write $3x+4y=-2$ in slope-intercept form by isolating $y$ :

$3x+4y=-2,\\4y=-3x-2,\\y=-\frac{3}{4}x-\frac{1}{2}$

Therefore, the slope of this line is $\frac{-3}{4}$ . To find the slope of a line perpendicular to it, multiply the reciprocal of the slope by -1 (take the negative reciprocal).

Therefore, the slope of a line perpendicular to $3x+4y=-2$ is:

$m_{perp}=-(-\frac{4}{3})=\boxed{\frac{4}{3}}$
