Question

First what you could do is find the slope

anonymous · Answer

idk how to do that im really bad with math could you help me get the answer?

luigi0210 · Answer

Well you would get the slope by using y2-y1/x2-x1where y2=2, y1=-1, x2=10 and x1=1

anonymous · Answer

slope is 4

luigi0210 · Answer

$$\frac{ (2)-(-1) }{ (10)-(1) }=4?$$

anonymous · Answer

x1 is 1 x2 is -1 y1 is 10 y2 is 2 correct?

anonymous · Answer

could you just give me the answer plz?

luigi0210 · Answer

Well the slope is 1/3.. and all you do is plug this into the point slope form formula. so Using the point (1, -1) we get $$y+1=\frac{ 1 }{ 3 }(x-1)$$
Should I continue or can you finish it from here?
