Billie walks 1.5 miles in half an hour. What is Billies walking speed in miles per hour?
In general speed=Distance over time
so in this case for instance
speed= 1.5 miles over .5 hours= 3 and the miles over hours!
Hope this helps!
It has 2 solutions i believe
I would say a but not 100% sure.
The functional equation of the line is f (x)=a*x+b
you have already a: -4 -->f (x)=-4 x+b
Now you can use the point (3;-3)
3 is the x-coordinate and -3 the f (x)-coordinate
--> -3 = -4*(3) + b Now you can solve it
-3 = -12+b (+12)
b = 9
ANSWER: f (x) = -4x + 9
Download an app called Photomath then it will answer it for you with work and explaining
