What is the point-slope form of a line with slope 2 that contains the point
(1, 3)?

y=2x+1

Step-by-step explanation:

A(1;3)  and m=2

y-yA=m(x-xA)

y-3=2(x-1)

y-3=2x-2

y=2x+1; or 2x-y+1=0

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)
