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:
The distance is 8 between (7,9) and (-1,9)
Step-by-step explanation:
For:
(X1, Y1) = (7, 9)
(X2, Y2) = (-1, 9)
d=(−1−7)2+(9−9)2√
d=(−8)2+(0)2√
d=64+0√
d=6–√4
d=8
Given:
Body length (meters) Mean Speed (meters/seconds) <span>4 0.89 </span>
4.5 0.83 4 0.76 6.5 0.94 5.5 0.94
The horizontal axis is the x-axis. The values reflected in this axis is the body length of the shark.
The vertical axis is the y-axis. The values reflected in this axis is the mean speed.
Graph your own scatter plot.
point 1 (4, 0.89)
point 2 (4.5, 0.83)
point 3 (4, 0.76)
point 4 ( 6.5, 0.94)
point 5 (5.5, 0.94)

This is a physics problem.
The law is that the momentum is preserved: total momentum before collsion = total momentum after collision
Momentum before collision = 80 kg.m/s - 100 kg.m/s = -20 kg.m/s
Then answer is b. - 20 kg.m/s
