In exercises 5-8, information is given about a particle moving along a line in the xy-plane. Use the information to find parametric equations for the x- and y-coordinates of the particle at an arbitrary time t. 5. Velocity = (3,– 1) and position at time t= 0 is (2, 3). 6. Velocity = (1,– 1) and position at time t= 0 is (1, -5). %3D

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
