Answer:
38
Step-by-step explanation:
To find the value of f(6), we substitute the value 6 where x is into the function. You would get:
7(6) - 4
42 - 4
f(6) = 38
<span>Since you already have the equation in y = mx + b form, which is called the slope-intercept form, with m = slope and b = y-intercept, you can graph it easily with that information. The 3 is the y-intercept. That means point (0, 3) is where the line crosses the y-axis. Plot that point first. The slope, m = -(1/5). The slope is the rise (up or down) over the run (left or right), or rise/run. -(1/5) can be thought of (-1)/5 or as 1/(-5). Both ways are correct and work. After plotting (0, 3), using m = (-1)/3, start at (0, 3) and count one unit down, and three to the right. That's a second point on your graph. If you want a third point, you can go back to the original point, (0, 3), and now use the slope as 1/(-5). That is, from (0, 3), go 1 unit up and 5 to the left. That is a third point. Now draw a line through all three points. </span>I hope that this is the answer that you were looking for and it has helped you.
To find the answer, you must find the midpoint of their x-coordinates and their y-coordinates. To do that, you take the average between their x and y-coordinates.
So, in this case, it is:
x: (12+12)/2 = 24/2 = 12
y: (7-3)/2 = 4/2 = 2
So, the answer is: (12,2)
