When the equation (2y=10x+14) is written in (y=mx+c) form, what will be the slope?
Answer and explanation
Correct answer: 5
Dividing both sides of 2y=10x+14 by 2 gives y=5x+7. In y=mx+c, the coefficient of x is m, which represents the slope; hence the slope is 5. Here, 7 is the y-intercept, not the slope. Exam tip: First simplify the equation into y=mx+c form, then identify the coefficient of x.
