Answer:
Part A: Option C
Part B: Option B
Explanation:
Part A:
We have to find the equation of a straight line having x-intercept at (3,0) and y-intercept at (0,2).
Now, using intercept form of straight line equation we can write the equation of the required straight line is
⇒
⇒
So, option C is correct. (Answer)
Part B:
See the graph of the straight line provided.
The straight line passes through the points (10, 80) and (20, 100)
Therefore, the slope of the straight line is given by
therefore, option B is correct. (Answer)
