Traza el grafico de la función y= ax+b, En cada caso y escribe la ecuacion de la función
A) Si a = 2 y b = 1
B) pasa por los puntos (2, 2) y a = 3

a)

The graph is on the figure with the red line

b)

And the equation would be:

The graph is on the figure with the blue line

Step-by-step explanation:

Part a

We know that a=2 and b =1

The general expression is given by:

The graph is on the figure with the red line

Part b

For this case we know that a=3 and we know a point given (2,2). Then we can find the value of b like this:

And the equation would be:

The graph is on the figure with the blue line

$12. that is my answer.
