Write an equation in point slope form of the line that passes through the point (6,-5) and has the slope 1/2

babymother [125]

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

$y - y_1 = m(x - x_1)$

where

m is the slope

( x1 , y1) is the point

From the question we have the final answer as

$\huge y + 5 = \frac{1}{2} (x - 6) \\$

Hope this helps you
