This week we are still studying Equations of Linear Relations Lesson. After studying the fourth lesson: Slope-Point Form. Let my memory not only stay in this lesson but also recall the knowledge of the first few lessons.
The point-slope form of the equation of a line is y-y1=m(x-x1), where m is the slope of the line, and (x1,y1)represents a point on the line. To determine the equation of a line in higher grade math courses, the point-slope equation, y-y1=m(x-x1), is used more frequently than the slope-y-intercept equation,y=mx+b.
#Note: The slope-point equation is used when we have the slope of a line and the coordinates of any point on the line. When using this method to determine the equation slope-y-intercept form, y=mx+b.
Here is the question that Hard to solve by me 😂，However, after the explanation of the teacher and classmates, he suddenly realized that such a simple question
