PL HELP ME What is a system of linear equations 

is a collection of one or more linear equations involving the same day of variables

Step-by-step explanation:

Here's an example of such a system:

ax + by = c

dx + ey = f

It contains 2 linear equations that may or may not be equivalent.  The goal is to find a single point, if such a point exists, that satisfies both of these linear equations.  If there is such a point, then the solution is unique.  If it can be shown that the two equations are equivalent, then there are an infinite number of solutions.  The third possibility is that no solution can be found, in which case the lines never intersect.

Among the several methods one can use to solve such a system of linear equations are 1) elimination by addition/subtraction; 2) graphing; 3) matrix operations; 4) determinants; 5) substitution.

answer: b)

step-by-step explanation:

its a dot plot because since the score is not high numbers.
