Question 929635
Find the slope using 13 for y2 and 7 for y1 , -5 for x2 and -2 for x1
{{{ (y2-y1)/(x2-x1) }}}
{{{ (13-7)/(-5-(-2)) }}}
{{{ (13-7)/(-5+2) }}}
{{{ 6/(-3) }}}
-2
So the slope M is -2
Use y = Mx + b as a template and use -2 for M , -2 for x and 7 for y
from the point (-2,7)
 {{{7 = (-2)(-2) + b }}}
 7 = 4 + b
add -4 to each side
 3 = b
We have slope M = -2 and b = 3 so our equation is
y = -2x + 3
