Write the equation of the line given the slope and the point that it passes through. m = 2/7
point = (1, 2)

slope (m)= 2/7

X1= 1

y1= 2

formula from equation of the line:

1. Y2 - Y1/ X2 - X1 ( if you know 2 point )

2. y - y1 = m × ( x - x1 ) (if you know the slope and 1 point )

3. mx + c = y ( if you know the slope and the y-axis )

because the known gradient and 1 point, then use the formula number 2.

let's get into the formula:

y - y1= m × (x -x1)

y - 2 = 2/7 × ( x - 1 )

y - 2 = 2/7x - 2/7

y= 2/7x - 2/7 + 2

y = 2/7x + 12/7

i think the answer is b
