well, do you mean the distance between the two lines..not necessarily points because their linear equations... If so, Well, if you think about it, when the lines cross the y axis, the first one crosses the y axis at (0,-11) and the second one...

Hi, For this question, recall that the x-intercept occurs when y = 0 and therefore we get: x - 8(0) - 16 = 0 x = 16 or (16,0) = x-intercept Now, the y-intercept occurs when x = 0 and therefore we get: 0 - 8y - 16 = 0 -8y = 16 y = -2 or (0,-2) = y-intercept I hope that helps...

2 tanx sinx = √3 tanx => 2 tanx sinx - √3 tanx = 0 => tanx (2sinx - √3) = 0 => tanx = 0 or sinx = √3/2 => x = kπ or x = kπ + (-1)^k (π/3) => x = { 0, π/3, 2π/3, π, 2π } taking x ∈ [0, 2π]

If a graph has an inflection point, the slope changes from + to - at that point. (or vice versa). As such, the slope of a tangent line at that point must be zero. NOW, which of those answers are of the form: y = 0x + b or more commonly y = b always, tony
