Slope From Two Points

The slope formula is given by $$m = \frac{y_2 - y_1}{x_2 - x_1}$$ , where (x_1, y_1) and (x_2, y_2) are two points on the line.

The slope is $$\frac{-4 - 7}{-6 + 4} = \frac{-11}{-2} = \frac{11}{2}$$ .

The slope is $$\frac{5 - 2}{4 - 1} = \frac{3}{3} = 1$$ .

The correct setup is $$\frac{0 + 5}{-9 + 2} = \frac{5}{-7}$$ .

The slope is $$\frac{10 - 4}{6 - 3} = \frac{6}{3} = 2$$ .

A positive slope indicates that the line rises as it moves from left to right.

A negative slope indicates that the line falls as it moves from left to right.

The slope of a horizontal line is 0.

The slope of a vertical line is undefined.

This means that for every 1 unit increase in x, y increases by 3 units.
