The answer will be option c which is short dash 3 over 4.
What is the slope?
Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.
Given points are:(1,9) and (3,6)
The slope of the line will be calculated as:-
y = mx + c
9 = m+c
6 = 3m+c
By solving the above linear equations we will get the value of m which will be our slope.
m = -3/2
Hence the answer will be option c which is short dash 3 over 4.
