Answer:
1/2
Step-by-step explanation:
2x+y =4
Lets solve for y so the equation is in slope intercept form
Subtract 2x from each side
2x-2x+y = -2x+4
y = -2x+4
The slope is-2
When we want a perpendicular line, the slope is the negative reciprocal
-(1/-2)
+ 1/2
The slope of the new line is 1/2
Answer:
C, 3
Step-by-step explanation:
By creating a best line of fit you can get the sets of points (16,50) and (12,40)
Using these to find the slope we can get 
-10/-4 is 2.5 The best approximation would be C, because if you round it up to the nearest number you would get 3.
Inside the square root shouldn't be negative, so x must be negative in order to form positive number inside the root.
if x = 0, y = 0
if y = -1, y = -1
if y = -4, y = -2
if y = -9, y = -3
the points lie on the graph (0,0), (-1,-1), (-4,-2), (-9,-3)
Isabella drove 600m.
Mia drove 300 more than Isabella=(600+300)m
=900m.
David drove=8.5km=8500m
Therefore, Distance David drove in meters combined of both distances of Mia and Isabella =[8500-(600+900)]m
=(8500-1500)
=7000 meters or 7 km.
