The y-intercept represents the price of the computer last Monday.
Step-by-step explanation:
The y-intercept is the point on a graph where x equals zero. Also, the y-intercept is the output value in an equation when x equals zero.

Therefore, the y-intercept represents the price of the computer last Monday.
Answer:
Blank 1: 64° (or 32°, depending on what the label applies to)
Blank 2: 42
Step-by-step explanation:
It is a common mistake to believe you have solved the problem when you have found the value of the variable(s) in the problem. You have correctly found the values of n (42) and m (9). However, that is not what the problem is asking for.
We cannot tell if the value (1/2n+11)° is referring to angle DAB, or to angle CAB. In any event, (1/2n+11)° = (1/2×42 +11)° = 32°.
If that is angle CAB, then angle DAB is twice that value, 64°.
If that is angle DAB, then angle DAB is 32°.
