PLS HELP I WILL GOVE BRAINLIEST

these problems are always tough b/c they want you to translate normal thinking into math jargon  :D   soooo....

Step-by-step explanation:

they use the point slope formula... which looks like

y = = m(x - )

where ( , )  are the x , y coordinates of some point you're given.. sooo

they give us two points.. so we can put either one of those into the formula.. but we also have to find m.... or the slope ... to find m.. use the slope equation of

m = ( - ) / ( - )  

call either point  P1  and P2 ... i'll pick the top point as P1  and bottom as P2

then

m = ( -3 -1 ) / ( 1 - 3 )

m = -4 / -2

m = 2     ( yay  :) )

now use either point and plug it into the point slope formula, i'll use P1

y - 1 = 2(x-3)   ( this is the answer they are looking for )
