If (m+c=15) and (c=6) in (y=mx+c), what is the slope?

Answer and explanation
Correct answer: 9
In the form (y=mx+c), m represents the slope. Given m+c=15 and c=6, we get m+6=15. Therefore, m=15-6=9. Hence, the correct answer is 9. Option 8 is incorrect because subtracting 6 from 15 gives 9. Exam tip: In y=mx+c, identify m as the slope and c as the y-intercept.
