Answer:
Equation of the line that passes through the point (-2,7) and has a slope of zero is given as
Step-by-step explanation:
Equation of line is given as
-----------(1)
Here
Substituting values in equation (1)
So we have 2 variables here: tacos and orders of nachos.
When we translate the paragraphs into equation:
Now, in this situation we can make use the elimination method by converting 3n to -27n.
Add both equations:
So we find that one taco costs $2.75.
We can plug this into any of the first two equations to find n:
So one order of nachos cost $1.40.
