What is the independent variable in a line equation?

What is the independent variable in a line equation?

Algebraically, a linear equation typically takes the form y = mx + b, where m and b are constants, x is the independent variable, y is the dependent variable. In a statistical context, a linear equation is written in the form y = a + bx, where a and b are the constants.

What is the independent variable in a slope equation?

y = a + bx where a is the y-intercept and b is the slope. The variable x is the independent variable andy is the dependent variable.

What is the constant in a linear equation?

A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y. a is the constant term or the y intercept. It is the value of the dependent variable when x = 0.

Is Y intercept a dependent variable?

Algebraically, a linear equation typically takes the form y = mx + b, where m and b are constants, x is the independent variable, y is the dependent variable. The y-intercept is used to describe the dependent variable when the independent variable equals zero.

How does the Y-intercept affect a graph?

Analysis: What effect does changing the y-intercept of an equation have on the graph? Increasing a y-intercepts moves the graph up. Decreasing a y-intercept moves the graph down. 4 Write an equation using the new slope and same y-intercept as the original equation.

Is Correlation the same as slope?

The value of the correlation indicates the strength of the linear relationship. The value of the slope does not. The slope interpretation tells you the change in the response for a one-unit increase in the predictor. Correlation does not have this kind of interpretation.

What is slope of a regression line?

 The slope, b, of a regression line is almost always important. for interpreting the data. The slope is the rate of change, the. mean amount of change in y-hat when x increases by 1. ˆ y = a+ bx.
