You can find the slope of a line perpendicular to this line by using the points and going through (y2− y1) (x2 − x1) ( y 2 - y 1) ( x 2 - x 1), or you can just nab it right out of the slope-intercept form! Yes, the slope of this line is 3 4 3 4.

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)
