Answer:
7.8 rounded to the nearest whole number would be 8.
Step-by-step explanation:
-6 would be x1
7 would be y1
-1 would be x2
1 would be y2
Take these numbers and plug them into the distance formula:


0.5(4)+c=-1, so c= -3. Therefore, y=0.5x-3.
Answer:
f(1) = 2
Step-by-step explanation:
To find f(1), substitute x = 1 into f(x), that is
f(1) = 1² + 3(1) - 2 = 1 + 3 - 2 = 2
