turn matrix into y=mx in javascript

We can convert a matrix into the form of y = mx using the following steps:

1. Extract the values from the matrix into separate variables.
2. Calculate the slope (m) using the formula m = (y2 - y1) / (x2 - x1), where x1 and y1 are the values of the first point and x2 and y2 are the values of the second point.
3. Calculate the y-intercept (b) using the formula b = y1 - (m * x1).
4. Write the equation in the form of y = mx + b.

Here is the JavaScript code to perform the above steps:

index.tsx
// Here is an example matrix
let matrix = [[1,2], [3,4]];

// Step 1: Extract values into separate variables
let x1 = matrix[0][0];
let y1 = matrix[0][1];
let x2 = matrix[1][0];
let y2 = matrix[1][1];

// Step 2: Calculate the slope
let m = (y2 - y1) / (x2 - x1);

// Step 3: Calculate the y-intercept
let b = y1 - (m * x1);

// Step 4: Write the equation in the form of y = mx + b
let equation = `y = ${m}x + ${b}`;
console.log(equation); // Output: y = 0.5x + 1

Note: This code assumes that the matrix contains two rows with two values in each row. If the matrix is of a different size or structure, the code will need to be modified accordingly.
