Question

what is the equation of blue line?

Answer 1

Answer:

equation of blue line  :   y = 2x + 3

Step-by-step explanation:

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

To find equation:

find slope: $\frac{y2-y1}{x2-x1}$

               :  $\frac{5-3}{1-0}$

               : 2

• the y-intercept is at 3.

Find equation:

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

                              y = 2x + 3
