Hello from MrBillDoesMath!
Answer: y = 2x - 7
Discussion:
Divide both sides of the equation by 2:
2y /2 = (4x-14)/2 = 4x/2 -14/2
or
y = 2x - 7
Thank you,

Answer:
$10 per kilogram
Step-by-step explanation:
To eliminate the decimals,multiply everything by 10
0.4.........4
4.00.........40
4 kilos = $40
1 kilo = $10 (40/4)
5300 and 6000 is the elevation in miles
Y = -4x + 2
3x + 2y = 6 (or in y-intercept form y=-3/2x + 3)
2x - y = 7 equals y = 2x -7 in y-intercept form. This means that the line has a positive slope and therefore goes upwards. This cannot be a potential equation because the line shown is clearly pointing downwards.
y=5 indicates that the line is a horizontal line that neither points upwards or downwards. This cannot be a potential equation because the line is pointing downwards.
The only possible equations left are y= -4x + 2 and 3x + 2y = 6, both of which graph a line pointing downwards because their slopes are negative. Hope this helps!
