Question

When solving a system of equations graphically, when would you need to estimate the solution? Explain.

Answer 1

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.

Answer 2

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.
