You are given coordinate values and a formula that tells you what to do with them. All you need to do is put the values in the formula and do the arithmetic.

<h3>Points</h3>

You are given points (2, -3) and (6, 4). The slope formula refers to the two points as (x1, y1) and (x2, y2). It does not matter which is which.

If we use the points in the same order they are given, then we can see that ...

x1 = 2
y1 = -3
x2 = 6
y2 = 4

<h3>Formula</h3>

Using these values in the given formula, we find the slope to be ...

$m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{4-(-3)}{6-2}=\dfrac{7}{4}$

The slope of the line through the given points is 7/4.

A train travels 3.5 kilometers on a straight track with grade of 1 degree 10'. What is the vertical rise of the train distance?

denpristay [2]

The answer is
h = AB sin tetha,
tetha is <span>1 degree 10' = 1.1°, and AB = 3.5km

the vertical rise is h = 4.7</span>
