Question 1207024
what is the slope of a line containing points (2,-1) and (3,5)
Using the slope formula m ={{{(y2 - y1)/(x2 -x1)}}}
x1 = 2
x2 = 3
y1 = -1
y2 = 5
m ={{{(5 - (-1))/(3 - 2)}}} = {{{6/1}}}
m = 6 is the slope
Create the equation using y - y1 = m(x - x1)
y -(-1) = 6(x - 2)
y + 1 = 6x - 12
y = 6x -12 - 1
y = 6x -13
which is
{{{ graph( 300, 200, -6, 10, -15, 10, 6x-13) }}}
