find the slope between two points in go

To find the slope between two points in Go, we need to get the coordinates of the two points and apply the slope formula.

The slope formula is:

main.go
slope = (y2 - y1) / (x2 - x1)

Here is an example function that calculates the slope between two points:

main.go
package main

import (
    "fmt"
    "math"
)

func main() {
    x1, y1 := 0, 0
    x2, y2 := 2, 4
    slope := getSlope(x1, y1, x2, y2)
    fmt.Printf("The slope between (%d, %d) and (%d, %d) is %.2f", x1, y1, x2, y2, slope)
}

func getSlope(x1, y1, x2, y2 int) float64 {
    return float64(y2-y1) / float64(x2-x1)
}
318 chars

In this example, we define the two points as (0,0) and (2,4). We then call the getSlope() function to calculate the slope between these two points. The getSlope() function takes four integer arguments, which are the coordinates of the two points. It then returns the slope as a float64 value.

We use the float64 type to ensure that we get a decimal value for the slope. Finally, we format the output to display the slope with two decimal places using the %.2f format specifier in the fmt.Printf() function.

The output of the above program would be:

main.go
The slope between (0, 0) and (2, 4) is 2.00

This means that the slope between the two points is 2, indicating a positive slope with a rise of 2 units for every run of 1 unit.
