What is the equation of blue line?

equation of blue line  :   y = 2x + 3

Step-by-step explanation:

coordinates: ( 0 , 3 ) , ( 1 , 5 )

To find equation:

find slope:

               :  

               : 2

Find equation:

using the formula: y = mx + b ...........where m is slope and b is y-intercept

                              y = 2x + 3

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.
