Find the slope of the line through each pair (1,-19),(-2,-7)

Answered by admin @



The slope of the line passing through the given points (1, -19) and (-2, -7) is -4.

Given the following points:

  • Points on the x-axis = (1, -2)
  • Points on the y-axis = (-19, -7)


To find the slope of the line passing through the given points (1, -19) and (-2, -7):

The slope of a line refers to the gradient of a line and it is typically used to describe both the direction and steepness of an equation of a straight line.

Mathematically, the slope of a line is given by the following formula;

Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}

Substituting the points into the above formula, we have;

Slope. \;m  = \frac{-7 \;- \;[-19]}{-2\; - \;1}\\\\Slope. \;m  = \frac{-7\; + \;19}{-3}\\\\Slope. \;m  = \frac{12}{-3}

Slope, m = -4

Therefore, the slope of the line passing through the given points is -4.
