Step-by-step explanation:
If a line is passing through the point (a,b) and has a slope m, then the equation of the line in point-slope form is given by :-

Given: A line that includes the point (6, 1) has a slope of 9.
The equation of line in point-slope form: 
Hence, the required equation in point slope form: 
Answer:
Step-by-step explanation:
49b² - 81 = (7b)² - 9 ²
by identity : 49b² - 81 = (7b - 9)( 7b + 9)
