To find the equation of line q, we need to determine its slope and use the point-slope form of a linear equation.Step 1: Find the slope of line p.The equation of line p is given as
. The slope of a line in the form
is the coefficient of x. Therefore, the slope of line p is -4.Step 2: Determine the slope of line q.Since line q is perpendicular to line p, its slope will be the negative reciprocal of the slope of line p. The negative reciprocal of -4 is
.Step 3: Use the point-slope form to find the equation of line q.The point-slope form of a linear equation is given by
, where
is a point on the line and m is the slope. We are given that line q passes through the point
, so we can use this point and the slope we found in step 2.Substituting the values into the point-slope form, we have:
Simplifying further:
Expanding the right side:
Simplifying the fraction:
Adding 1 to both sides:
Combining like terms:
Therefore, the equation of line q is
