The equation which represents a linear function for the variable y is y=12r-5. Option B is the correct option.
<h3>What is linear function?</h3>
Linear function is the function in which the highest power of the unknown variable is one. Linear functions are used to model the real life problem in the mathematical expressions.
The linear function with dependent variable y and independent variable x can be written as,
y=mx+c
Here, m is the slope of the line represented by the function and c is the y intercept.
The equation given in the problem are,
2ry+y= 9
y=12r-5
3y+r2+t=0
4r+2(y-1)=0
The second option is similar to the standard linear function.
Hence, the equation which represents a linear function for the variable y is y=12r-5. Option B is the correct option.

Answer:
4
Step-by-step explanation:
250 - 10 = 240
240/50 = 4.8
You cannot buy 8/10 of a net meaning you can only buy 4
Distance = speed* time
D= constant rate *1/4 miles/hour
Answer:
B. -8
Step-by-step explanation:
F(x) = 2x
F(-4) = 2(-4) = -8
