To find the equation of line q, we need to use the point-slope form of a linear equation, which is given by:
where
is a point on the line and
is the slope of the line.Since line q is parallel to line p, it will have the same slope as line p. The slope of line p can be found by rearranging the equation of line p in slope-intercept form (i.e.,
), where
is the slope and
is the y-intercept.Rearranging the equation of line p, we have:
Simplifying further, we get:
From this equation, we can see that the slope of line p is
.Now, we can use the point-slope form to find the equation of line q. We know that line q passes through the point
, so we can substitute these values into the point-slope form:
Simplifying further, we get:
Therefore, the equation of line q is
