Question

The equation of a line is shown below.

y = fraction reading 1 over 5x - 9

What is the equation of a line which is perpendicular to this line and passes through (1, 58)?

y = 5x - 63

y = -5x + 63

y = 9x - 63

y = 9x + 63

Answer 1

wats the slope of the GIVEN line ?

Answer 2

\(\large y = \frac{1}{5}x - 9\)

Answer 3

1/5

Answer 4

compare it wid

\\(\large y = mx + b\)

Answer 5

Yes, slope of given line is 1/5

Answer 6

we want to find the slope of line thats perpendicular to this

Answer 7

u knw any relation between slopes,
when lines are perpendicular ?

Answer 8

The recipricol right?

Answer 9

negative recipricol

Answer 10

half correct

Answer 11

yes! negative reciprocal !!

Answer 12

:)

Answer 13

so what will be the slope of the required line ?

Answer 14

So it's -1/(1/5)

Answer 15

simplify

Answer 16

-1/0.2 = -5?

Answer 17

yup !

you knw slope \(-5\), and u knw a point \((1, 58)\)

Answer 18

can u write the equaiton of line ?

Answer 19

y=-5x+b
58=-5x+b
58=-5+b
63=b?
