Answer:
the slope is 4
Step-by-step explanation:
-you have to solve for y;keep y by itself on one side of the equation
-you start by subtracting 4x on both sides(to get rid of it on the left side of the equation). you end up with -y= -4x+6
-y must be positive when it is alone, so to make it a positive, you have to divide both sides of the equation by -1. you end up with y= 4x-6
-so now that we have y by itself and positive, we can identify the slope. (the slope will always be what is right next to x, in this case it is 4). so the slope is 4
Answer:
C
Step-by-step explanation:
I'm sure it's right hope this helps
-- Driving at 30 mph for 20 minutes (1/3 hour), you cover 10 miles.
-- Walking at 3 mph for 10 minutes (1/6 hour), you cover 0.5 mile.
-- Average speed = (total distance covered) / (time to cover the distance)
= (10.5 miles) / ( 1/2 hour)
= 21 miles per hour.
