Question

Find the slope of the line

Answer 1

Slope of a Line

Suppose we know the line passes through points A(x1,y1) and B(x2,y2). The slope can be calculated with the equation:

`\displaystyle m=(y_2-y_1)/(x_2-x_1)`

Two clear points are visible in the graph of the figure: (0,1) and (4,0).

Note: I'm assuming each division of the grid has a measure of one unit.

Applying the formula:

`\displaystyle m=(0-1)/(4-0)=(-1)/(4)=-(1)/(4)`

The slope of the line is -1/4.
