Perpendicular to y = 4x + 2 and passing through the point (0, -4)

Question

anonymous · Answer

For perpendicular lines, you just flip the current slope your given and change the sign. You keep the same y-intercept. So you answer would be y=-1/4x+2

Woops, while the slope part is true, we'll often have a `new` y-intercept! :)

$$\Large\rm y=-\frac{1}{4}x+b$$Plug in the coordinate that they gave you to find your new y-intercept.$$\Large\rm -4=-\frac{1}{4}\cdot 0+b$$

Hm. I was taught different, but I can see how you got that.
