Question

Decide what can be used to determine the equation of a line when you have two points, but no slope.






a.


slope-intercept form


c.


point-slope form




b.


general form


d.


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

Answer 1

@phi

Answer 2

D is what I would do myself.

Answer 3

\[m = \frac{y_1 - y_2}{x_1 - x_2}\]
\[y = mx + b\]
You have (x1 , y1) , (x2 , y2)
You could then plug in one of those points and solve for b, the y intercept.
