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 $\frac{1}{4}$

For each of the equations below, solve for y in terms of x. !<br> a. 2x – 3y = 12

ira [324]

Answer:

$\large\boxed{y=\dfrac{2}{3}x-4}$

Step-by-step explanation:

$2x-3y=12\qquad\text{subtract}\ 2x\ \text{from both sides}\\\\2x-2x-3y=12-2x\\\\-3y=12-2x\qquad\text{divide both sides by (-3)}\\\\\dfrac{-3y}{-3}=\dfrac{12}{-3}+\dfrac{-2x}{-3}\\\\y=-4+\dfrac{2}{3}x$
