Answer:
Slope = 3
distance travelled after 1 second = 7 feet
Step-by-step explanation:
From the equation: y = 3x + 4 where y is the the distance travelled in feet and x is the time taken in seconds.
The slope of the graph = 3 ( the coefficient of x)
After 1 second, the distance travelled;
y = 3(1) + 4 = 3 + 4 = 7
y = 7 feet
Therefore, the distance cover after 1 second is 7 feet
