girlgoyleh. · Answer

those are the choices. we use y=mx+b right?

haleyelizabeth2017 · Answer

Yep! :) so the slope is going to be 7....now we just need to find the y-intercept! :D

haleyelizabeth2017 · Answer

Do you have an idea of what the y-intercept is?

girlgoyleh. · Answer

how do we identify the y intercept?

haleyelizabeth2017 · Answer

It is where the line intercepts the y-axis so in this case it is going to be +5 :)

Now this leaves us with y=7x+5 :)

haleyelizabeth2017 · Answer

Did you understand how I got that?

girlgoyleh. · Answer

I think so, the beginning of the line starts at 5 so thats the y axis?

haleyelizabeth2017 · Answer

yep :) When x is zero, whatever y is, that's the intercept :)
