Use the graphing tool to determine the intercepts.
x-intercept =
y-intercept =

Step-by-step explanation:

The x-intercept is the x-value where the graph crosses the x-axis. Here, that is at x=3.

Similarly, the y-intercept is the y-value where the graph crosses the y-axis. Here that appears to be at about y=-12.

the answer is 28

step-by-step explanation:

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
