Hello from MrBillDoesMath!
The first choice (y = 2x) is NOT the blue line because it has twice of the slope of the line y=x. That is, for a given positive x value the graph of y= 2x appears above the black line which is not the case for the blue line shown.
The second choice (y =.001x) is a possibility but the multiplier .001 is so small I think the graph of that line would be "close" to the x-axis. I don't think it's the blue line.
y = -x. Now here we can say NO! That line goes through the origin all right but has a slope of -1 so is heading "downward" from left to right. That is not the blue line either.
Well, then, it seems that the last equation ( y = 1/2x) is the only remaining reasonable answer.
Regards, MrB.
Answer:
( 1/2 ; 1/2 ) and ( 1 ; 2 )
Step-by-step explanation:
y = 2x².............1
y = 3x-1............2
2x²=3x-1
2x²-3x+1 = 0
(2x-1)(x-1) = 0
x = 1/2 or x = 1
y = 1/2 or y = 2

Answer:
(3x + 4)(x - 3)
Step-by-step explanation:
3x² - 5x - 12 = (3x + 4)(x - 3)
7 miles divided by 4/7 hour
copy dot flip
7 miles * 7/4 hour
49/4 miles/ hour
d = rt
1 miles = 49/4 * t
divide each side by 49/4
1 / (49/4) = t
4/49 =t
it takes 4/49 of an hour
