Anyone could kindly me an explaination would too : )

The equation is y=5x
Now make a table as such
X
Y.
Now we give a x a value and plug it in the equation.
Let’s say x=1
This implies that y=5*1=5
Now put these values in the table
X. 1
Y. 5
Give more values to x and keep filling the table
After that plot the graph
Hope this helps for your future graph problems too :)
