Question

someone solve this before i go insane...

Answer 1

Answer:

here,

m=(-1,-1) and f=(2,-4)

x1= -1 y1= -1

x2= 2 y2= -4

we know that,

d= root{(x2-x1)² + (y2-y1)²}

= root{( 2-(-1))² +(-4-(-1))²}

= root{(2+1)² + (-4+1)²}

= root{(3)² + (-3)²}

= root { 9+9 }

= root {18}

= root {2×3×3}

= root {2×3²}

=3root (2) units
