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

y = x - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - x - 3 ← is in slope- intercept form

with slope m = -

Give the slope of a line m then the slope of a line perpendicular to it is

= - = - =

The line crosses the y- axis at (0, - 1 ) ⇒ c = - 1

y = x - 1 ← equation of perpendicular line

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
