D.

Intercept Form

Detailed Explanation

Choice A is correct. Choice A is the correct answer. Definition of forms. 1. Point-Slope: yy1=m(xx1)y - y_1 = m(x - x_1) shows mm and (x1,y1)(x_1, y_1). 2. Slope-Intercept: Shows mm and y-intercept (0,b)(0, b). 3. Standard: Shows intercepts easily, but not slope directly. Strategic Tip: The name tells you what it shows! Choice B is incorrect because it shows the y-intercept specifically, not any general point. Choice C is incorrect because it hides the slope. Choice D is incorrect because it shows two intercepts.

Key Steps:

The correct answer is Point-Slope Form
