Ch3 Concept and Formulas Review Flashcards
For y=mx how to calculate unknown constant m when a paired value of x and y were given? Saying the value gien for x and y pair as x1 and y1.
replace the x and y in formula using given paied value y1=m×x1 next step we solve this equation to get m as x1×m÷x1=y1÷x1 so m = y1÷x1
