Question 257387
Here are the points:
(3,-1) and (5,3)
step 1 - find the slope using the formula
{{{m = (y2-y1)/(x2-x1)}}}
putting in our coordinates, we get
{{{m = (3-(-1))/(5-3)}}}
which is
{{{m = 2}}}
step 2 - put slope and a point into the equation
{{{y = mx + b}}}
{{{3 = 5*2 + b}}}
solve for b to get
{{{b = -7}}}
step 3 - write the answer as
{{{y = 2x - 7}}}
