How do I graph this?​
vfiekz [6]

See attachment of the graph of the inequalities x + 7y ≤ 49 and 6x + y ≤ 48

<h3>How to graph the inequalities?</h3>

The inequalities are given as:

x + 7y ≤ 49

6x + y ≤ 48

The domain and the range are:

x ≥ 0

y ≥ 0

This means that, we plot the inequalities x + 7y ≤ 49 and 6x + y ≤ 48 under the domain and the range x ≥ 0 and y ≥ 0

See attachment of the graph of the inequalities x + 7y ≤ 49 and 6x + y ≤ 48
