Answer:
2y=4 is a linear function
Step-by-step explanation:
Since 2y=4 is the same as 2y¹=4, then a degree of 1 makes the function linear, aka. a straight line.
Answer:
first and third
Step-by-step explanation:
Consider
y =
x + 3 ( multiply through by 2 )
2y = x + 6 ← third equation
4a-8=28
add 8 to both sides to start to isolate the variable (a)
-8+8 cancels each other out
28+8=36
4a=36
to completely isolate the variable divide both sides by 4
4a÷4=a
36÷4=9
a=9
