2-129.
Consider the system of equations at right:
What is the parent of each equation?
Both equations are equations of lines.
Solve this system algebraically.
Multiply the first equation by
, then use elimination.
Now substitute the value found forinto the equation and solve for . Find where the two graphs intersect.
The graphs intersect at the solution to both equations.
Explain the relationship between parts (b) and (c) above.
