help with what

2. ineedyouubiebs

wait a sec let me write it

3. ineedyouubiebs

If a line has a slope of -2/5 and passes through the points (3,7), write an equation for this line in slope intercept form

@jim_thompson5910

5. friendswithdogs

you want to use the point-slope equation:$y-y _{1}=m(x-x _{1})$ next you plug in your values and you get y-7=-2/5(x-3).

6. friendswithdogs

distribute -2/5 and add 7 to both sides and you get y= -2/5x + 6/5 +7

7. friendswithdogs

then just add 6/5 and 7 and your final answer will be y= -2/5x + 8.2. you can leave that in fraction form if you want

8. ineedyouubiebs

After I distribute it'll be y-7=-2/5x+6/5

9. friendswithdogs

yes, you distribute then add 7 to both sides

10. ineedyouubiebs

I think it'll be y-29/5=-2/5z

11. friendswithdogs

in slope intercept form you want y to be isolated

12. ineedyouubiebs

but is what I said correct?

@friendswithdogs

14. friendswithdogs

im not sure how you got -29/5

15. ineedyouubiebs

i cant subtract fractions in my calculator

16. friendswithdogs

after you distributed to get $y -7=\frac{ -2 }{ 5 }x +\frac{ 6 }{ 5 }$ use your calculator to add 7 to 6/5 and that should be your answer

17. ineedyouubiebs

I got y=-2/5x+41/5
