The equation of the line in point-slope form is \(y - 5 = 3(x + 1)\), which corresponds to option A.
Explicação
## Step 1The given equation is
. The slope of this line is
.## Step 2The slope of a line perpendicular to a given line is the negative reciprocal of the slope of the given line. Therefore, the slope of the line perpendicular to the given line is
.## Step 3The point-slope form of a line is given by \(y - y_1 = m(x - x_1)\), where
is the slope and \((x_1, y_1)\) is a point on the line.## Step 4Substituting the slope
and the point \((-1, 5)\) into the point-slope form, we get \(y - 5 = 3(x - (-1))\), which simplifies to \(y - 5 = 3(x + 1)\).
