X = 2.5 would be your answer. Hope this helps!
Answer:
y = -3x
Step-by-step explanation:
It is easiest to try the answers for x=1.
a) y = 1/-3 = -1/3 ≠ -3
b) y = 1 ≠-3
c) y = 3(1) = 3 ≠ -3
d) y = -3(1) = -3 . . . . . this rule matches the table
A^2 + b^2 =c ^2
7.3^2 + 4.8^2 = c^2
C^2= 76.33
C= square root of 76.33
C= 8.7
Which is d
-x - y = -5
y = x + 1
-x -(x + 1) = -5
-x - x - 1 = -5
-2x = -5 + 1
-2x = -4
x = -4/-2
x = 2
y = x + 1
y = 2 + 1
y = 3
solution is : (2,3)
