I wonder if you mean to write in place of

If you meant what you wrote, then we have
If you meant to write (the cube root of 256), then we could go on to have
slope (m ) = , y - 1 =
( x - 2)
The equation of a line in ' point- slope form 'is
y - b = m (x - a)( m is the slope and (a , b ) a point on the line )
To calculate m use the ' gradient formula'
m = (y₂ - y₁ )/(x₂ - x₁ )
let (x₁, y₁ ) = (2 , 1) and (x₂, y₂ ) = (14 , 31) ← values chosen from table
m = (31 - 1 )/(14 - 2 ) = =
equation in point- slope form using m = and (a,b )= (2 , 1)
y - 1 = ( x - 2)
