Answer: Equation of line in point-slope form is
and Equation of line in slope-intercept form is .
Explanation: The given points are and
The slope (m) of the the line passing through these two points is given by the formula,
Now, the equation of line with slope, m=2 and passing through point is .
Substituting the known values
-------------------------------------------- (1)
This is the equation of line in point-slope form.
(ii) In order to write the equation of line in slope-intercept form, using eqn 1
subtracting 4 from both sides
This is the equation of line in slope-intercept form where, slope=2 and intercept=2.
