According to the slope formula: Slope = \(\displaystyle\frac{{{y}_{2}-{y}_{1}}}{{{x}_{2}-{x}_{1}}}\)
\(y_2 = 6.1\)
\(y_1 = 3.1\)
\(x_2 = -5.5\)
\(x_1 = -2.5\)
Therefore: \(\displaystyle{6.1}-\frac{{3.1}}{{-{{5.5}}}}--{2.5}\)
Since negative negative is positive you are left with: 3/-3
Therefore the answer is -1.
