Question

draw the graph of y = 2x - 1​

Answer 1

Answer:

Sometimes, especially after a little experience, you can tell from the "form" of the equation what the "shape" of the graph is. If you can tell the shape then it makes plotting the graph easier, but for the moment let's just try to plot it without knowing the shape beforehand. To do this I am going to use a table of values. I am going to choose some values for the variable x, calculate the corresponding value of y and then record my results in a table. So, for example when x = 1 then y = 2 1 + 1 = 3 and when x = 2 then y = y = 2 2 + 1 = 5. Here is my table including these two values of x and a few more.
