Question

Write the equation of a line in slope-intercept form that is perpendicular to the line y=3/5x-1 and passes through the point (-9, 4).

Answer 1

what is the slope of a perpendicular line?

Answer 2

i dont know thts all i have and im confused

Answer 3

it's the negative reciprocal.

Answer 4

-9

Answer 5

negative reciprocal of 3x/5 is not -9

Answer 6

then?

Answer 7

y=mx+b where m is the slope.

Since the perpendicular slope is the negative reciprocal, you flip the fraction representing the slope and you multiply it by -1.

Answer 8

so would it be -5/3x-11
