The example of a right angle is that it's exactly 90°, the acute angle is less than 90°, and the obtuse angle is more than 90° but less than 180°.
Answer:
The standard form of
is -2 x + 3 y = 21.
Step-by-step explanation:
Here, the given expression is : y= 2/3 x +7
The standard form of the equation is ax + by = c
Now, simplifying the above expression:

or, 
or, -2x + 3y = 21
Hence, the standard form of
is -2x + 3y = 21.
