Determine whether the graphs of the equations are parallelperpendicular or neither?
Base on the slope of two linear equations (form: y = mx+b, where slope is m): - If slopes are equal, the 2 graphs are parallel - If the product of two slopes equals to -1, the 2 graphs are perpendicular. If none of the above, then the 2 graphs are neither parallel nor perpendicular.

How can you determine whether a system has no solutions by graphing?
If you graph the two functions defined by the two equations of the system, and their graphs are two parallel line, then the system has no solution (there is not a point of intersection).
How can you solve a system of equations?
The answer depends on whether they are linear, non-linear, differential or other types of equations.
Determine whether each equation is a linear equation If so write the equation in standard form and determine the x-intercept and y-intercept 1 8x - 3y 6-4x 2 5 - 2y 3x 3 5x - 2y 7?
Without any equality signs the expressions given can't be considered to be equations
What are two ways to determine whether a relation is a function?
Two ways to determine whether the relation is a function is use a mapping diagram or use a vertical line test.
The test is used to determine whether a function is one-to-one?
horizontal line
