Answer:
Please check the wording of the problem. The exact solution is (-5.75, -4.55).
Explanation:
The given points are marked on the attached graph. We are asked for an exact solution for the two lines formed by these points. As given, the points do not intersect anywhere near the point where it is said the curves intersect (-1.2, -4.8). Was this value a duplicate of the line point?
We can find an exact solution by mathematically calculating the slope and y-intercept for each line and solving through substitution. Since the data look suspect, L simply graphed the two lines for estimating the slope and y intercept to arrive at the linear equations noted on the attached graph. They cross at (-5.75, -4.55).
