Answer:
see the explanation
Step-by-step explanation:
we know that
When solving a system of equations graphically, the solution is the intersection points both graphs.
so
You need to estimate the solution when:
a) both the x- and y-values for the intersection point are not integers.
b) the value of at least one coordinate is between integers.
c) the intersection point does not fall on a grid line.
Graphs in which both the x- and y-values for the intersection point are not integers need to be estimated because the lines do not intersect on a grid line where it is easy to read what the values are.
