Answer:
Slope = -⅓
Explanation:
The equation for the slope of a straight line is
m = (y₂ - y₁)/(x₂ - x₁)
The line passes through (-1, 2) and (-4, 3).
m = (3 - 2)/[-4 - (-1)]
= 1/(-4 + 1)
= -⅓
The slope of the line is -⅓.
The Figure below shows the graph of your line through (-1, 2) and (-4, 3) with a slope of -⅓.
