Machine Learning often uses line graphs to show relationships.
Formula
A line graph displays the values of a linear function: y = ax + b(Straight)
(Angle)
(Start value)
Linear means straight. A linear graph is a straight line.
Formula
The graph consists of two axes: x - axis (horizontal) and y - axis (vertical).const xValues = [];
const yValues = [];
// Generate values for (let x = 0; x <= 10; x += 1) {
xValues.push(x);
yValues.push(x);
}
// Define Data const data = [{
x: xValues, y: yValues, mode: "lines"
}];Formula
// Define Layout const layout = {title: "y = x"};// Display using Plotly
Plotly.newPlot("myPlot", data, layout);The slope is the angle of the graph.
value in a linear graph: y = a x In this example, slope = 1.2
let slope = 1.2;
const xValues = [];
const yValues = [];
// Generate values for (let x = 0; x <= 10; x += 1) {
xValues.push(x);
yValues.push(x * slope);
}
// Define Data const data = [{
x: xValues, y: yValues, mode: "lines"
}];
// Define Layout const layout = {title: "Slope=" + slope};// Display using Plotly
Plotly.newPlot("myPlot", data, layout);Intercept is the start value of the graph.
value in a linear graph:
Formula
y = ax +b
Formula
In this example, slope = 1.2 and intercept=
let slope = 1.2;
let intercept = 7;
const xValues = [];
const yValues = [];
// Generate values for (let x = 0; x <= 10; x += 1) {
xValues.push(x);
yValues.push(x * slope + intercept);
}
// Define Data const data = [{
x: xValues, y: yValues, mode: "lines"
}];
// Define Layout const layout = {title: "Slope=" + slope + " Intercept=" + intercept};// Display using Plotly
Plotly.newPlot("myPlot", data, layout);
