I think 42? I'm not completely sure but that's my guess :)
Answer:
AB=24cm and BC=6cm
Step-by-step explanation:
Answer:
-7/5
Step-by-step explanation:
The slope of a perpendicular line is the "negative reciprocal" of the slope of the original line. so just switch the numbers and put the top number into a negative.
a = ( 1 , 6 )
b = ( 4 , 9 )

Now just need to put the coordinates in the above equation :



And we're done...♥️♥️♥️♥️♥️
To answer the question above, know that one of the way of writing the equation of the line is through the point - slope form which is generally expressed as,
y - y1 = m(x - x1)
where m is the slope and x1 and y1 are the abscissa and ordinate of the point, respectively.
Substituting the given data to the equation above,
y - 5 = -1(x -0)
By simplification we get an answer of
y = -x + 5
