math,question
okay i really don't understand this problem.
It says:
Prove the pointslope equation property which is :
Pointslope equation(an nonvertical line with slope m and containing a point (X1,Y1) has the pointslope equation of yy1=m(xx1).
Now show that any point (x2,y2) on the line described must satisfy the equation, and that any point satisfying the equation must be on the line described.
