Maths - Linear Models
What is a linear model?
A model which works with a straight line.
When creating a linear model, how do you need to change $y = mx + c$?
Instead of using $y$ and $x$ you use variables which reflect the context.
What is the general ice cream sales equation?
$\text{ice cream sales} = m \times \text{weather} + c$
What’s a common critique of a linear model?
It predicts impossible negative values.
What does the gradient in a linear model reflect?
How much one variable changes as the other changes.
What does the $y$-intercept in a linear model reflect?
The initial result without being affected by the $x$ variable.
In a car value over time graph, what does the gradient reflect?
The amount of worth that the car loses per unit of time.
In a car value over time graph, what does the $y$-intercept reflect?
The initial value of the car.
