To determine the equation of the line using two points, calculate first the slope with the equation,
m = (y2 - y1)/ (x2 - x1)
In this given,
m = (7 - 1)/ (2 - 0) = 3
Use the point-slope form of the equation where,
y - y2 = m (x - x2)
y - 7 = 3 (x - 2), y = 3x + 1
Thus, the equation of the line is y = 3x + 1
