Answer:
The answer is -18
Explanation:
Slope of a line is defined as the change in y coordinate of the line to the change in its x coordinate.
If m is the slope of a line. Slope can then be expressed mathematically as;
Slope(m) = ∆y/∆x
Where ∆y = y2-y1
∆x = x2-x1
m = y2-y1/x2-x1
Given the points (x1,y1) = (34,12)
(x2,y2) = (32,48)
Where x1= 34, y1= 12, x2 = 32, y2 = 48
Substituting this value in the formula for calculating slope we have;
Slope = 48-12/32-34
Slope = 36/-2
Slope = -18
Therefore the slope of the line is -18
