Answer:
(A) The slope of secant line is 18.
(B) The slope of secant line is h+16.
Step-by-step explanation:
(A)
The given function is
At x=3,
At x=9,
The secant line joining (3,27) and (9,135). So, the slope of secant line is
The slope of secant line is 18.
(B)
The given function is
At x=5,
At x=5+h,
The secant line joining (5,55) and . So, the slope of secant line is
The slope of secant line is h+16.
Answer:
Step-by-step explanation:
slope-intercept form:
Start with the given equation, and to find the slope, convert it to slope-intercept form by solving for y.
In this case, all you need to do is subtract 3x from both sides.
Here, the slope is -3. The slope of a parallel line will also be -3.
Now, we have 3 known variables. We have the slope and the x and y of a known point. Use those 3 knowns to solve for the 1 unknown, the y-intercept.
Finally, with the slope and the y-intercept, you can write the equation of the line:
