Question

find the slope of a perpendicular to the line y = 4x - 3

Answer 1

4

Answer 2

-4x+3

Answer 3

Slope of the give line
m1= 4
Therefore the slope of the required line
\[m_2= -\frac{1}{m_1} = -\frac{1}{4} \]

Answer 4

I agree....for a perpendicular line, the slope you need is the slope that is the negative reciprocal of the slope in the given equation. All that means is you " flip " the slope of the given line and change the sign. The slope of the given line is 4, which is the same as 4/1. The slope you need is -1/4...you see how I " flipped " the slope and changed the sign.
