The graph of an equation, in other words, is the graph of its solutions. It is the picture of those values of (x, y) that make the equation -- that statement -- true.Every first degree equation -- where 1 is the highest exponent -- has as its graph a straight line. (We prove...
The graph of a function is a straight line parallel to the x-axis. Which function could it be? A. y = 0 B. y = x C. y = x + 1 D. y = x^2 相关知识点: 试题来源: 解析 A。因为平行于 x 轴的直线上所有点的纵坐标都相同,只有 y = 0 是一条平行于 x 轴的直线。 反馈 ...
