Answer: slope = - 2

slope = rise/run

= (-6-6)/(3+3) = -12/6 = -2

Which is the slope for the equation that is perpendicular to y=-4x+3

zzz [600]

Answer:

$\frac{1}{4}$

Step-by-step explanation:

The equation for a line is y=mx + b where m represents the slope

If a line is perpendicular to another line, it's slope is the negative reciprocal of the other line's slope.

The reciprocal of -4 is $-\frac{1}{4}$

And the negative of that would be $\frac{1}{4}$

Check the picture below.

a(-1,2)\qquad b(7,14)\qquad
\qquad 1:3
\\\\\\
\cfrac{aP}{Pb} = \cfrac{1}{3}\implies \cfrac{a}{b} = \cfrac{1}{3}\implies 3a=1b\implies 3(-1,2)=1(7,14)

$\bf -------------------------------\\\\
P=\left(\cfrac{(3\cdot -1)+(1\cdot 7)}{1+3}\quad ,\quad \cfrac{(3\cdot 2)+(1\cdot 14)}{1+3}\right)

P=\left( \cfrac{-3+7}{4}~,~\cfrac{6+14}{4} \right)$
