Find the equation of the straight line passing through the point ( 0 , -1 ) which is perpendicular to the line y = -3/4x - 3

Perpendicular = opposite sign and reciprocal slope
Y = 4/3x + b
-1 = 0 + b, b = -1
Equation: y = 4/3x - 1

I’d go with b hope it

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
