A linear function refers to when the dependent variable (usually expressed by 'y') changes by a constant amount as the independent variable (usually 'x') also changes by a constant amount. For example, the number of times the second hand on a clock ticks over time, is a linear function.

So that's some number that's not going to change over time so we should be looking for that in our information.

To solve linear equations graphically, first graph both equations in the same coordinate system and check for the intersection point in the graph. For example, take two equations as 2x + 3y = 9 and x ? y = 3. Now, to plot the graph, consider x = {0. 1, 2, 3, 4} and solve for y.

So that's the slope that passes through these two points.

Using a Given Input and Output to Build a Model Identify the input and output values. Convert the data to two coordinate pairs. Find the slope. Write the linear model. Use the model to make a prediction by evaluating the function at a given x-value. Use the model to identify an x-value that results in a given y-value.

And the P variable is goingMoreAnd then empty box. So that means that the N variable is our Y variable. And the P variable is going to be the X variable. So whatever we would normally do to find the equation of a line here.

We can write our linear model like this: y = . 082x, where y is the cost of the bill, and x is the amount of electricity used. You can use slope-intercept form, which is y = mx + b, to write equations for linear models. m is the slope or rate-of-change, and b is the y-intercept.

A linear model example is a verbal scenario that can be modeled using a linear equation or vice versa. An example could be each pizza costs $10 and the delivery fee is $5, so the linear model would be y=10x+5, where y represents the total cost and x represents the number of pizzas.
