The slope of the given line is - 6 as per slope-intercept form.
What is the slope of a straight line?
The linear equation y = mx + c represents the slope-intercept form of a line passing through the point (x, y).
Here, 'm' is the slope and 'c' is the y-intercept of the given line.
The slope of a line that passes through points (x₁, y₁) and (x₂, y₂) is defined as:
m = (y₂ - y₁)/(x₂ - x₁)
Therefore, the slope of a line that passes through (-2, 8) and (-1, 2) is
= (2 - 8)/[- 1 - (- 2)]
= - 6/1
= - 6
