Answer:
y = -4x+15
Step-by-step explanation:
y=x/4+5 may be presented as y = 1/4 x + 5, where a=1/4, b=5
swapping numerator and denominator and inserting an opposite sign in a=1/4, we have:
1/4 --------> 4/1 -------> -4/1 = -4
y = -4x+n
Point (2,7) means that x=2, y=7 substitute it to the equation y=-4x+n, calculate "n":
7=-4*2+n ------> 7=-8+n -------> 7+8 = n -------> 15=n
substituting n=15 to the equation y=-4x+n, we get finally y=-4x+15

7/25 is correct answer dude
Answer:
(4,1)
Step-by-step explanation:
x+y=5
x- y=3
Add the equations together to eliminate y
x+y=5
x- y=3
--------------------
2x = 8
Divide each side by 2
2x/2 = 8/2
x = 4
Now we can find y
x+y = 5
4+y = 5
Subtract 4 from each side
4+y-4 = 5-4
y =1
