You by combing like terms
A) y=3x
You can plug in the given values (inputs) of x to see if it creates the number in y (output).
3*1=3
3*2=6
3*3=9
3*4=12
3*5=15
3*6=18
All these values are true, therefore the equation y=3x is the correct answer.

Answer:
Step-by-step explanation:
Answer: y=5x+3
Step by step explanation:
Perpendicular meaning that the product of the slope/gradient is -1 hence ...
-1/5 * x = -1
x = -1/-1/5
x = 5
The equation perpendicular to y=-1/5x-3 is y=5x-c
Now it contains the points (1,2)
x variable is 1 and y variable is 2 plug them into the line equation
2=5(1)-c
2=5-c
2-5=-c
-3=-c divide by -1
3=c
Hence the perpendicular equation is y=5x+3
Hopefully it’s correct :)
