Web2. Let P ( X, Y) be the given point (I changed the notation from ( x, y) ). The equation of a straight line is. y = m x + b, ( 1) where m is the slope (or gradient) and b is the value of y for x = 0 (in another words, b is the y axis intercept). Now we use the information that the line passes through P. The ( X, Y) coordinates must satisfy ( 1). WebFrom the function expression. For any function (not necessarily affine/linear), calculate the value for x= 0 x = 0. The value obtained is the y-intercept. Example: A curve of equation y= 3x2 +1 y = 3 x 2 + 1, with x =0 x = 0 is y =3×02+1 =1 y = 3 × 0 2 + 1 = 1, so 1 1 is the y-intercept. For an equation of a line of the plane, the equation ...

WebA Linear Function represents a constant rate of change. When plotted on a graph it will be a straight line. A graph may be plotted from an equation `y = mx + c` by plotting the intercept at `(0, c)`, and then drawing the gradient `m`, although it is normally easier to generate the points in a table and plot the graph..
