I am wanting to have the students answer with the equation “y=3x” and proportional equations such as this. I am not wanting to use tables, as my students can respond 3x, but are struggling with writing the equation on their own. Is there a way to have the students input a proportional equation and have it graded by Desmos?
Are they entering any proportional equation, or a specific one?
For a specific one:
targetEq=simpleFunction(`y-3x`,"x","y") studentEq=parseEquation(input.latex).differenceFunction("x","y") #the specific values don't really matter below check= targetEq.evaluateAt(2,1) = studentEq.evaluateAt(2,1) and targetEq.evaluateAt(3,2) = studentEq.evaluateAt(3,2)
You could also use pattern matching to just check for the right form.
