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

Answer:

Helena is correct.

Step-by-step 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

$y - y'= \frac{y''-y'}{x''-x'}\times (x-x')$

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

So, Helena is correct.
