Question
find the x - intercept and the y - intercept of the line below. click on
one\ if applicable. (a) x - intercept: (b) y - intercept:
Step1: 确定x轴截距定义
x轴截距是直线与x轴交点的横坐标,此时y = 0。
Step2: 观察图像找x轴截距
从图中可知直线与x轴交点横坐标为3,所以x - intercept为3。
Step3: 确定y轴截距定义
y轴截距是直线与y轴交点的纵坐标,此时x = 0。
Step4: 观察图像找y轴截距
该直线与y轴无交点,所以y - intercept为None。
