Question

step 5: determine the intersection point: approximately (-9, -2)
which best describes moises error?
moises incorrectly determined the slope of the line.
moises incorrectly determined the y-intercept of the line.
moises incorrectly graphed one or both of the stated equations.
moises incorrectly approximated the point of intersection shown on the graph.

Explanation:

To determine Moises' error, we analyze the options. The key here is about the intersection point approximation. But typically, if the issue is with the graphing of the equations (like plotting lines wrong), that would lead to a wrong intersection. However, the option about incorrectly approximating the intersection (but usually, the main error in such cases is graphing the equations wrong, but wait—no, the question is about which best describes. Wait, actually, when finding intersection, if the lines are graphed wrong (one or both), then the intersection point would be wrong. But let's think: the options are about slope, y-intercept, graphing equations, or approximating intersection. The error here is likely that Moises incorrectly graphed one or both equations, leading to a wrong intersection. Wait, no—wait, the step is "determine the intersection point: approximately (-9, -2)". But maybe the actual intersection from the correct graphs is different, so the error is in graphing the equations (so the lines are plotted wrong, hence intersection is wrong). Alternatively, if the graphs were correct, the approximation of the intersection (the point) would be wrong, but "incorrectly approximated" would mean reading the graph wrong, but "incorrectly graphed" means drawing the lines wrong. So the best answer is that Moises incorrectly graphed one or both of the stated equations, because if the graphs are wrong, the intersection point is wrong. Wait, but let's check the options again. The options are: slope, y-intercept, graphing equations, or approximating intersection. So the error in determining intersection point would be due to wrong graphing (since if you graph the equations wrong, the intersection is wrong) or wrong approximation. But "incorrectly approximated" would be about reading the graph, but "graphing the equations" is about plotting them. So the correct option is "Moises incorrectly graphed one or both of the stated equations." Wait, no—maybe the actual error is in graphing the equations, so the lines are not plotted correctly, leading to a wrong intersection. So the best answer is that option.

Answer:

Moises incorrectly graphed one or both of the stated equations. (The option: "Moises incorrectly graphed one or both of the stated equations.")
