Ymx+b equation examples. Let us see how we can represent y = mx b on a graph using an example Example Graph \(y = 3x 2\) Solution Compare the given equation with \(y=mxb\) We get \m=3\\02cm b=2\ The yintercept of the line will be \(0,b)=(0, 2)\ We will first plot the point (0, 2) on the graph and label it as \(A\). The first example equation is Y = 2x 1 over y = mx b The video then shows you how to breakdown the equation into manageable sums using fractions to represent the data, and then presents the formula for interpreting the answer from these sums onto the graph coordinates The second and third e. The point (0, 7) is the yintercept, so we can use y mx b giving the equation 3 7 y x Example 2 What is an equation of a line containing the points (4, 3) and (2, 8)?.

Linear functions are those where the independent variable xnever has an exponent So for example they would not have a var such as 3x2in them write the equation of a straight line It is of the form y = mx b. Interpret the equation y = mx b as defining a linear function, whose graph is a straight line;. Give examples of functions that are not linear For example, the function A = s2 giving the area of a square as a function of its side length is not linear because its graph contains the points (1,1), (2,4) and (3,9), which are not on a straight line.
