Slope = (-3/4); contains the point (12,7)

see explanation

Step-by-step explanation:

Assuming you require the equation of the line

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = - and (a, b) = (12, 7), thus

y - 7 = - (x - 12) ← in point- slope form

Multiply through by 4

4y - 28 = - 3(x - 12) ← distribute

4y - 28 = - 3x + 36 ( add 3x to both sides )

3x + 4y  - 28 = 36 ( add 28 to both sides )

3x + 4y = 64 ← in standard form

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)
