Question

plzzz helpppp!
Choose the equation of the line passing through the point (1, -5) and perpendicular to y = 1/5x - 10.

y = 5x + 10

y = 5x

y = -5x - 10

y = -5x

Answer 1

if the line is to be perpendicular to the line with slope of 1/5, what must the slope be then? do you know the relationship between perpendicular slopes?

Answer 2

slope is 5

Answer 3

no.... the relationship is that the product of perpendicular slopes is -1. in other words,
\[\huge m_1 \cdot m_2=-1 \rightarrow \frac{1}{5} \cdot m_2=-1 \]

so what must \(\large m_2= \) ????
