Question

What is the equation of blue line?

Answer 1

equation of blue line : y = 2x + 3

Explanation:

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

To find equation:

find slope:
`(y2-y1)/(x2-x1)`

:
`(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
