When the line \\(8x-4y=16\\) is written in the form \\(y=mx+c\\), what is its slope \\(m\\)?

Answer and explanation

Correct answer: 2

Starting with \\(8x-4y=16\\), rearrange to get \\(-4y=16-8x\\), and then divide by \\(-4\\): \\(y=2x-4\\). Comparing this with \\(y=mx+c\\), the coefficient of \\(x\\) is the slope, so \\(m=2\\). Therefore, option A is correct. Option B results from a sign error while isolating \\(y\\). Exam tip: always express the equation in \\(y=mx+c\\) form before reading the slope.
