Calculate 6

Calculate the distance of a point A[0, 2] from a line passing through points B[9, 5] and C[1, -1].

Correct answer:

d =  0.2

Step-by-step explanation:

Ax=0;Ay=2 Bx=9;By=5 Cx=1;Cy=1  l=(CxBx)2+(CyBy)2=(19)2+((1)5)2=10 S2=(CyBy) Ax+(CxBx) Ay+Cx ByBx Cy=((1)5) 0+(19) 2+1 59 (1)=2 d=S2/l=(2)/10=15=0.2
