Let's graph every equation on the same coordinate plane:
Cucumber and pepper will never reach the same heights on the same day, let's express the equations in the slope-intercept form:
[tex]\begin{gathered} _{\text{ }}Cucumber\colon y=2x-4 \\ _{\text{ }}Pepper\colon y=2x-5 \end{gathered}[/tex]
They have the same slope but they have different y-intercepts, therefore the lines are parallel. If two lines are parallel they never cross each other. The same happens for corn, which equation is:
[tex]_{\text{ }}Corn\colon2x+3[/tex]
Answer:
[tex]_{\text{ }}Corn\ne Cucumber,Pepper_{}[/tex]
The same combination of variables have different solutions.
