I believe it is standard. The equation for standard is ax+by+c.
Answer:
yes
Step-by-step explanation:
For the relation to be a function, there must only be one corresponding value of y (range) for any value of x in the domain, that is a one-to- one relationship
This graph displays this feature and is a function.
the slope goes by several names
• average rate of change
• rate of change
• deltaY over deltaX
• Δy over Δx
• rise over run
• gradient
• constant of proportionality
however, is the same cat wearing different costumes.
and to get it, we simply need two points off of the straight line, hmm let's use the ones in the picture below.

SOLUTION
Consider the property, opposite angle of a cyclic quadrilateral are supplementary
hence

Recall that

Hnece, we have that

Then

Hence
x=17
Since

Therefore
The measure of angle NOP is 68⁰
Answer; 68⁰ (The fourth Option )
