You have the equation y = 5x and an x value, x = 13.
1. Substitute the x value into your equation.
y = 5(13)
2. Simplify by performing the multiplication.
y = 65
Since you already know that x = 13, you can simply plug 13 in for x in the original equation.
Therefore, put 13 in place of x in y = 5x.
5 multiplied by 13 is 65.
So, y = 65.
To find the value of y at point x=13, we need to substitue x for its value in the equation. In other words, replace x with 13 in your problem.
`y=5x=>y=5*13=65`
