To find the equation of line v, we first need to find the slope of line u. We can do this by rearranging the equation of line u into slope-intercept form (y = mx + b), where m is the slope.Given:
Step 1: Distribute the
on the right side of the equation:
Step 2: Subtract 6 from both sides to isolate y:
Now we have the equation of line u in slope-intercept form:
. The slope of line u is
.Since line v is perpendicular to line u, the slope of line v will be the negative reciprocal of the slope of line u. Therefore, the slope of line v is
.Step 3: Use the point-slope form of a linear equation to find the equation of line v. The point-slope form is given by:
, where
is a point on the line and m is the slope.Given point:
Slope:
Substitute these values into the point-slope form:
Simplify:
Step 4: Rearrange the equation into slope-intercept form:
Combine like terms:
Therefore, the equation of line v in slope-intercept form is:
