The slope of the given line containing the given points is; 7.
The formula for slope of a line between two coordinates is;
Slope(m) = (y2 - y1)/(x2 - x1)
Now, let us take the last 2 coordinates which are;
(-1, 35) and (2, 56).
Thus, the slope is;
m = (56 - 35)/(2 - (-1))
m = 21/3
m = 7
Thus, the slope of the given line containing the given points is 7.
