Hey there!!
How do we find an equation?
We will need to find the slope and the y-intercept :
How do you find slopes?
Ans - In order to find slope, we will need to use the slop formula which is
( y₂ - y₁ ) / ( x₂ - x₁ )
Now let's take two points on the graph :
I would take ( 0 , 3 ) and ( 1 , 6 )
( 6 - 3 ) / ( 1 - 0 )
3 / 1
Hence, the slope is 3
The basic equation :
y = mx + b
m = slope and b = y-intercept
slope = 3
y = 3x + b
Now, let's take a coordinate and plug in the values :
... ( 1 , 6 )
6 = 3 + b
b = 3
The final equation : y = 3x + 3
Hope my answer helps!!
