Question

How do you find the slope of (2.78,10) and (3.05,12)?

Answer 1

Given two points `(x_0, y_0)` and `(x_1, y_1)`, the slope of a line through them is (change in `y`) / (change in `x`).

That is:

slope = `(y_1 - y_0) / (x_1 - x_0)`

In your case we have `x_0 = 2.78`, `y_0 = 10`, `x_1 = 3.05` and `y_1 = 12`.

So slope = `(12 - 10) / (3.05 - 2.78)`

`= 2/0.27 = 200/27 = 7.dot(4)0dot(7)`
