=> 7 centimeters convert to meters
In every 1 meter there are 100 centimeters
=> 7 / 100
=> 0.07
Therefore in 7 centimeters there are 0.07 meters.
7 cm is a whole number while 0.07 m is a decimal number
Scientific Notation of each numbers
=> 7 cm = 7 x 10^0
=> 7 m = 1 x 10^-2
Scientific notation by the way is an expression used by the scientist to make a
large number or very small number easy to handle.

The vertex would be the point on the right angle like the tip of the right angle
Andy's equation is incorrect and the correct equation of the line is y + 2= 3/4(x - 3)
<h3>How to determine the equation of the line?</h3>
The given parameters are:
Slope, m = 3/4
Point, (x,y) = (3,-2)
The equation of the line is calculated using:
y - y1 = m(x - x1)
Substitute the known parameters
y + 2= 3/4(x - 3)
From the question;
Andy's equation is y + 2 = 3/4(x - 9/4)
The above equation is different from the actual equation y + 2= 3/4(x - 3)
Hence, Andy's equation is incorrect and the correct equation of the line is y + 2= 3/4(x - 3)
