Question

Find a​ point-slope form for the line with slope 1/5 and passing through the point ​(​-6,-9​).

Answer 1

y=1/5x-39/5

Explanation:

y=mx+b (slope y intercept formula)

y=1/5x+b

take (-6,-9) and put in appropiate places

-9= -6/5+b

*multiply lhs and rhs by 5

-45= -6+5b

-45+6=5b

-39=5b

-5b=39

b=39/-5

y=1/5x-39/5
