Question 360683
y = 2x + 1 is a straight line.


Here's a graph of that equation.


{{{graph(600,600,-10,10,-20,20,2*x+1)}}}


here's the table of values for y = 2*x + 1 from x = -2 to x = 2


<pre>

               x	y
              -2       -3
              -1       -1
               0        1
               1        3
               2        5

It looks like you are forgetting to multiply first and then add.


in the formula 2 * x + 1, you need to do the multiplication first and then add.


if you put parentheses around the operations that need to be done first, then the equation would look like this:


(2 * x) + 1


if the value of x is 1, then 2 * 1 = 2 and then you add 1 to it to get 3.


follow the same procedure for all values of x and you'll be ok.
