The equation of line perpendicular to 4y = x-8 passing through (3,-3) is:
Step-by-step explanation:
Given equation of line is:
We have to convert the given line in slope-intercept form to find the slope of the line
So,
Dividing both sides by 4
Let m1 be the slope of given line
Then
Let m2 be the slope of line perpendicular to given line
As we know that produt of slopes of two perpendicular lines is -1
The slope intercept form of line is given by:
Putting the value of slope
to find the value of b, putting (3,-3) in equation
Putting the value of b in the equation
Hence,
The equation of line perpendicular to 4y = x-8 passing through (3,-3) is:

Answer:
f(x) = |x + 1| – 3
Step-by-step explanation:
The given graph is a transformed absolute value function.
The parent function is
The graph is obtained by shifting, g(x) from the origin (0,0) to (-1,-3).
The transformed function is of the form:
Where (h,k) is the vertex.
We substitute h=-1 and k=-3 to get:
When we simplify we get:
