If you would like to simplify 7x − 4y + 5z − 2x − 10y + z, you can do this using the following steps:

7x − 4y + 5z − 2x − 10y + z = 7x - 2x - 4y - 10y + 5z + z = 5x - 14y + 6z

The correct result would be 5x - 14y + 6z.

The point-slope form of an equation of a linear function:

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

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have two points (1, 4) and (-3, 6). Substitute:

$m=\dfrac{6-4}{-3-1}=\dfrac{2}{-4}=-\dfrac{1}{2}\\\\y-4=-\dfrac{1}{2}(x-1)$
