To find the equation of line d, we need to use the slope-intercept form of a linear equation, which is given by:
where
is the slope and
is the y-intercept.Since line d is parallel to line c, it will have the same slope as line c. The slope of line c is given by:
Now, we need to find the y-intercept (
) of line d. We know that line d passes through the point \((10, -9)\). We can use this point to find the y-intercept by substituting the values of
and
into the slope-intercept form:
Simplify the equation:
To isolate
, we need to add
to both sides of the equation:
Convert
to a fraction with a denominator of 7:
Now add the fractions:
So, the y-intercept of line d is
.Now we can write the equation of line d in slope-intercept form:
Therefore, the equation of line d is:
