Step-by-step explanation:
Answer:
The slope of the line is m = 2.
The y-intercept is (0,7).
The equation of the line in the slope-intercept form is y = 2 x - 7.
Step-by-step explanation:
The slope of a line passing through two points
and 
is given by 
We have that
,
, and 
Plug the given values into the formula for a slope:
.
Now, the y-intercept is
(or
, the result is the same).

Finally, the equation of the line can be written in the form
:
