Question

The equation of a line given two points needs to be found. Samuel claims that slope-intercept form will generate the equation and Helena claims that point-slope form will find the equation. Who is correct?

Answer 1

Helena is correct.

Explanation:

The slope intersept form of the line is

y = m x + c

where, m is the slope and c is the intersept.

The point slope form of the equation is

`y - y'= (y''-y')/(x''-x')* (x-x')`

So, if there are two points are given, the equation of line is found by the point slope form.

So, Helena is correct.
