Notice that since the two graphs didn’t meet at \(x = 1\) we left a blank space in the graph. Do NOT connect these two points with a line. There really does need to be a break there to signify that the two portions do not meet at \(x = 1\). Sometimes the two portions will meet at these points and at other times they won’t.

To graph the equation of a line, we plot at least two points whose coordinates satisfy the equation, and then connect the points with a line. We call these equations "linear" because the graph of these equations is a straight line. There are two important things that can help you graph an equation, slope and y-intercept.

We're asked: Do the points on the graph below represent a function? So in order for the points to represent a function, for every input into our function, we can only get one value. So if we look here, they've graphed the point--it looks like negative 1, 3, so that's the point negative 1, 3.

To see why this is we draw the graphs of the left hand side of the original equation f(x) = x 2 − 1 and the right hand side g(x) = 2x − 3. We see that the parabola f(x) and the straight line g(x) do not intersect. It’s easy to see that we cannot calculate the point of intrsection simply because there is no such point. Example 4
Because every logarithmic function of this form is the inverse of an exponential function with the form y = b x, y = b x, their graphs will be reflections of each other across the line y = x. y = x. To illustrate this, we can observe the relationship between the input and output values of y = 2 x y = 2 x and its equivalent x = log 2 ( y ) x ...

Let the slope-intercept form of the line be: y = mk + b, where 'm' is the slope and 'b' gives the y-intercept. If 2 lines are perpendicular, then the product of their slopes is −1. y + 4x = -12 is equivalent to y = -4x - 12. The slope of y + 4x = -12 is (-4) thus the slope of the perpendicular line will be m = 1/4. Now we can write y = (1/4)x ...

Equations featuring x and y (and no x^3 or y^2 etc.) are straight lines.. The gradient of a line is a measure of how steep it is. If the gradient is small, the slope of the line will be very gradual, but if the gradient is big, the line will be quite steep.
