Answer:
27 N
Step-by-step explanation:
Since force varies directly with acceleration, we can introduce a constant, k, and write
When force is 15, acceleration is 5, so plug it into the equation and solve for k:
Now, to find force, we use a = 9 and k = 3, so
The force is 27 N
By definition, the Slope-Intercept Form of the equation of a line is:
Where "m" is the slope and "b" is the y-intercept.
Then, to find the slope and the y-intercept of the line given in the exercise, you only need to solve for "y", in order to write the equation in Slope-Intercept Form:
Now you can identify that the slope is:
And the y-intercept is:
Therefore, the answer is:
