If you go to a reliable sores that would be hard to understand but there is google that ca help you with what you need
What we need to do first, is to write the equation of the line through points A and B.
the slope of the line through A(3, 7) and B(-4, 9) is

the equation of the line is :

C(a, 1) is on this line so it must satisfy the equation:
