Question

A line passes through the points (4 -1) and (2 3). what is the slope of the line

Answer 1

4/-2

Explanation:

the slope formula is y2-y1/x2-x1

plug in the coordinates to the formula.

3-(-1)/2-4 = 4/-2

the slope should be 4/-2

Answer 2

slope = -2

Explanation:

`Slope=(y_(2)-y_(1))/(x_(2)-x_(1))\\\\=(3-[-1])/(2-4)\\\\=(3+1)/(-2)\\\\=frac{4}{-2}\\\\=-2`
