how to make a graph?

hello!
Is theere a way to make a grapf in CALC using y=a*x+b ???

Many thanks!

Could you make your main question a bit more specific than “how to make a graph?”
And could you explain the relation to your previous question, linked to by @horst? How is this question different, except for the formula?
Thanks!

Use the answer here and adapt the formula.
