The equation of a line is y = -x. Will this produce a horizontal, vertical, or diagnol line? - O Horizontal.

- O Vertical

-Diagonal

Diagonal

Step-by-step explanation:

Graph y = -x. The coefficient of the x term, or the "m" in y = mx + b format, represents the slope, so the slope of the line must be -1. There is also no number adding to or subtracting it, or the "b," which represents the y-value of the y-intercept - thus the y-intercept is just (0,0).  

Thus, plot the y-intercept, (0,0), and graph the rest of the line with the given slope, -1. (A graph is attached below.) This gives us a diagonal line.

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)
