Question 304151
Find the distance, d, between: (-3,1) and (-1,6)
{{{d = sqrt((x[2]-x[1])^2+(y[2]-y[1])^2)}}} Substitute:{{{x[1] = -3}}},{{{y[1] = 1}}},{{{x[2] = -1}}}, and {{{y[2] = 6}}}
{{{d = sqrt((-1-(-3))^2+(6-1)^2)}}} Simplify.
{{{d = sqrt(2^2+5^2)}}}
{{{d = sqrt(4+25)}}}
{{{d = sqrt(29)}}}
{{{highlight(d = 5.4)}}} Rounded to the nearest tenth.
