To help draw a straight line graph ... 𝑦 equals 𝑚𝑥 add 𝑐, where 𝑚, the coefficient of the 𝑥 term, is the gradient or slope of the line. The constant, 𝑐, is the 𝑦-intercept.

The gradient is the measure of slope of a line ... (3), and \(c\) is the \(y\)-intercept (1). The equation is \(y = 3x + 1\) Practise reading and plotting quadratic graphs with this quiz.

c\) is the number where the line crosses the \(y\)-axis. This is the \(y\)-intercept. To draw a graph of \(y = mx + c\) for given values of \(x\): Use the pairs of values in the table to list the ...

Python allows free creation of plots, unlike expensive, stagnant graphing calculators. Import NumPy and Matplotlib for basic ...

use the scales of the axes and find how many units you go up or down for each unit you move right. To work out the equation of a line from a graph, find the gradient and the \(y\)-intercept.
