Final answer:
To write the equation of a line in point-slope form, we use the formula y - y1 = m(x - x1), where (x1, y1) is the given point and m is the slope.
Step-by-step explanation:
To write the equation of a line in point-slope form, we use the formula y - y1 = m(x - x1), where (x1, y1) is the given point and m is the slope.
Given the point (0, 1) and the slope 2, we substitute these values into the formula to get y - 1 = 2(x - 0).
After simplifying, we find that the correct equation in point-slope form is: y - 1 = 2x.
