Question

FInd the equation of the lines described. Put your final answer in slope-intercept form. Do not graph.
slope= 3, y-intercept form (0, -4)

hero · Answer

Hint: Use y = mx + b

anonymous · Answer

but what is mx+b? i understand thats the slope-intercept form , but how do i use it?

hero · Answer

m = 3
(x,y) = (0,-4)

Substitute those values in, then solve for b

anonymous · Answer

so m is a variable for slope? right? if so then im on track! i understand now thanks,!

hero · Answer

If you understand it, then you should be able to post the slope intercept form of the line.

anonymous · Answer

this is what i have...
y= mx=b
-4=3(0) =b
-4=0+b
*simplifies*
-4=b
is that right?

anonymous · Answer

y=mx +b..my bad

hero · Answer

Yes, but you still have to put it in slope intercept form. Basically slope intercept form is where you include m and b values in the formula

hero · Answer

Actually, you can still write the formula and only include m and b:

You would get y = 3x -4

anonymous · Answer

so what would my final answer look like?

anonymous · Answer

oh lol, okay thanks

hero · Answer

I just showed it to you.
