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

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 ...

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.

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.

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.
