Answer:
Option A) y = -2x + 15
Step-by-step explanation:
step 1
Find the slope of the line perpendicular to the given line
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
The equation of the given line is
so
The slope of the given line is 
therefore
The slope of the line perpendicular to the given line is
step 2
Find the equation of the perpendicular line in point slope form
we have
substitute
---> equation in point slope form
Convert to slope intercept form
Answer:
B. Increasing in x < -1 and decreasing in x > -1.
Step-by-step explanation:
We are given the graph of a function and is required to find the interval in which the function is increasing, decreasing or constant.
Now, from the graph we can see that the critical point i.e. the point at which the graph changes the direction is x = -1.
We observe that the function on the left side of x = -1 is going upwards to reach the point x = -1 and the function on the right side of x = -1 is going downwards.
Hence, we get that the function in increasing in x < -1 and decreasing in x > -1.
Answer:
5
Step-by-step explanation:
(y2-y1)/(x2-x1), when you plug the numbers into the formula, you should get 5
