find the equation of the straight line passing through the point (0,-1) which is perpendicular to the line y=-3/4x-3
1 answer:
Answer:
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 this form
with slope m = -
the slope of a perpendicular line is the negative reciprocal of m, hence
=
(0 , - 1 ) is the y-intercept ⇒ c = - 1
y = x - 1 ← equation of perpendicular line

Answer:
The parameters in the parent function are:
- the parameter correspondig to - 3 in the given function is 0 in the parent function.
- the parameter corresponding to 1/2 in the given function is 1 in the parent function, and
- the parameter corresponding to - 1 in the given function is 1 in the parent function.
Explanation:
The given function is .
The parent function of . The parameters of the given function are -1 (which is mutlyplying the value of cosine, 1/2 which is multiplying the argument (x), and - 3 which is subtracted.
In the parent function, those values are 1, 1, and 0.
It may help you representing the parameters in the given function with letters:
Then, in the given function A = - 1, B = 1/2, and C = -3.
Now, you can write the parent function:
Then, the parameters are A = - 1, B = 1, and C = 0.
