Answer:
slope = 2 because it goes up by 2 and across 1
10 = 2(1)+b
10=2+b
-2 -2
b = 8
y intercept = 8
equation: y = 2x+8
yes it is proportional because it has a constant rate of change or slope
Answer:
Johnny and his family left home at 10:00.
Step-by-step explanation:
First, You add all of the minutes up,
45+20+10= 75
Then convert the minutes to hours,
