Question

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

y = 5x + 10 y = 5x y = -5x - 10 y = -5x

Answer 1

gradient of the line is \[m _{l} = \frac{1}{5}\]

for a perpendicular \[m _{p}=-\frac{1}{m _{l}}\]

to the gradient of the perpendicular is

\[m _{p}= -5\]

in point slope form the line is

\[y -(-5) = -5(x - 1)\]

simplify to find the equation of your line

Answer 2

Is it y= -5x-10?

Answer 3

1st simplifcation is

y + 5 = -5x + 5

Answer 4

y=-5x!

Answer 5

correct
