问题 What is the equation of a line parallel to y = 4x - 12 that crosses the y-axis at 3?
选项
答案 y = 4x + 3
解析 For two lines to be parallel, their slopes must be equal; therefore, in the standard equation y = mx + b, m = 4. You are given that the line crosses the y-axis at 3, so the y-intercept(b)must be 3. If you substitute 4 for m and 3 for b in the standard equation, you get y = 4x + 3.
