Linear Relationships Assessment Review

The y-intercept represents the starting value of the dependent variable when the independent variable is zero.

The slope indicates the rate of change of the dependent variable with respect to the independent variable.

'm' represents the slope of the line, and 'b' represents the y-intercept.

The slope can be found by selecting two points on the line and using the formula: slope = (change in y) / (change in x).

A positive slope indicates that as the independent variable increases, the dependent variable also increases.

A negative slope indicates that as the independent variable increases, the dependent variable decreases.

The y-intercept often represents the initial condition or starting point of a situation being modeled.

A system of equations has no solution if the lines represented by the equations are parallel and never intersect.

If two lines intersect at a point, it means that the system of equations has a unique solution at that point.

The formula is: slope = (y2 - y1) / (x2 - x1).
