Question
The choice that best defines the term "linear function" is,
- An equation that is the bomb diggity
- An equation that can be written in slope-intercept form
- An equation with an exponent in it
- An equation that has a slope but not a y-intercept
Hint:
Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.
The correct answer is: An equation that can be written in slope-intercept form
Linear function is an equation that can be written in slope-intercept form.
A linear function is of the form f(x) = mx + b where 'm' and 'b' are real numbers. A linear function represents a line, i.e., its graph is a line. Here,
- 'm' is the slope of the line
- 'b' is the y-intercept of the line
- 'x' is the independent variable
- 'y' (or f(x)) is the dependent variable
