The slope of the line that passes through the points (x1, y1) and (x2, y2) is computed as follows:


m=(y_2-y_1)/(x_2-x_1)

The slope of the line that passes through (-4, -11) and (3, 3) is:


m_1=(3-(-11))/(3-(-4))=(14)/(7)=2

The slope of the line that passes through (5, -2) and (6, -9) is


m_2=(-9-(-2))/(6-5)=-7

Yes, lines m and n intersect because their slopes are different
