Question

What is the slope of the line passing through the following points: `(3,15) ; (1,5)`?

Answer 1

Slope of the line `color(chocolate )(m = 5)`

Explanation:

Slope of a line knowing two points on it is given by

Slope `m = (y_2 - y_1) / (x_2-x_1)`

Given : `(x_1,y_1) = (3,15), (x_2,y_2) = (1,5)`

Slope `= m = (5-15) / (1-3) = (-10)/(-2 )= color (chocolate)(5`
