Question

Find the equation of the line that contains the given point and has the given slope. Let y be the dependent variable and let x be the independent variable.
Point (-1, -1), m =1/7


This is what I think you suppose to do but its not working for me....

y-y1=m(x-x1)
y=1/7x+1? am i doing this right?

Answer 1

y=1/7x+1/7?

Answer 2

y+1=1/7(x+1)
y+1=1/7x+1/7
y=1/7x-6/7

Answer 3

where did 6/7 come from?

Answer 4

i subtracted 1 from each side

Answer 5

Im sorry i confused is there a way to show me how you did it? u subtracted what from both sides?

Answer 6

point-slope formula is the top line
y-y1=m(x-x1)
distributed m on the 2nd line
y-y1=mx-mx1
added y1 to each side on 3rd line
y=mx-mx1+y1

Answer 7

ok

Answer 8

in your solution, i believe you forgot to distribute the 1/7 to the -1

Answer 9

to the positive 1, rather

Answer 10

I did and I see what you did now that was just my missing step. Thank you so much
