Answer:
Find the slope from a graph
Locate two points on the line whose coordinates are integers.
Starting with the point on the left, sketch a right triangle, going from the first point to the second point.
Count the rise and the run on the legs of the triangle.
Take the ratio of rise over run to find the slope. m = rise / run.
So the question if find y'' for 4y=cos2x
First, find y by dividing by 4. y = cos2x/4
Then, take the first derivative. y' = -sin2x/2
Then, take the second dervative. y'' = -cos2x
Answer:
C and E has All real numbers are solutions.
Step-by-step explanation:

Answer:
Should look like this
Step-by-step explanation:
y-intercept = 2
slope = 1
Answer:
x = 41/2
Step-by-step explanation:
I am assuming that we are finding 'x' when y = 9.
