Math Test #5 Vocab

Consistent System

A system of equations that has at least one solution

Dependent System

A system of equations that does not have a unique solution (infinitely many solutions) (two of the same exact lines graphed on top of each other)

Inconsistent system

A system of equations that has no solution (parallel lines —> no intersection)

Independent System

A system of equations that has a unique solution [intersection point (x,y)]

Extrapolation

This is predicting a value outside the range of known values

Interpolation

This is estimating a value between two known values

Point-Slope Form

y-y₁ = m(x-x₁)

Slope - Intercept Form

y = mx+b

Standard Form

Ax + By = C
