Question 243507
The slope of a line can be found using the following equation:
{{{m=(y2-y1)/(x2-x1)}}} ...or... {{{m=(y1-y2)/(x1-x2)}}}
.
We would then substitute the x and y values in the equation to determine the slope.
.
Let (-12,1) be (x1,y1)
Let (-14,5) be (x2,y2)
.
{{{m=(y2-y1)/(x2-x1)}}}
{{{m=(5-1)/(-14-(-12))}}}
{{{m=4/(-14+12)}}}
{{{m=4/-2}}}
{{{m=-2}}} <--- Here's the answer!
.
{{{m=(y1-y2)/(x1-x2)}}}
{{{m=(1-5)/(-12-(-14))}}}
{{{m=(-4)/(-12+14)}}}
{{{m=(-4)/2}}}
{{{m=-2}}} <--- we get the same answer with the second equation.
.
Done! :)
