Explanation:

To find the equation of a line with two points (no slope given), first, the slope formula $m=\frac{y_2 - y_1}{x_2 - x_1}$ (where $(x_1,y_1)$ and $(x_2,y_2)$ are the two points) is used to calculate the slope. Then, with the slope and one of the points, a form like point - slope form ($y - y_1=m(x - x_1)$) can be used to find the line's equation. Options a (slope - intercept form needs slope and y - intercept), b (general form is a result, not a way to find from two points), and c (point - slope form needs a slope, which we don't have initially) are not suitable. So the correct method is described in option D.

Answer:

D. slope formula, then use one of the given points to find the equation
