Question

Write an equation of the line perpendicular to y = -4x – 3 that contains the point (7, 3).

Answer 1

Hint: if the lines are Perpendicular their Slopes m1*m2 = -1

Answer 2

The gradient of the given line=\(m_1\)
The gradient of the required line=\(m\)
\(m*m_1=-1\)
\(m_1=-4\)
\(m*-4=-1\)
\(m=\large\frac{-1}{-4}\)
\(m=\large\frac{1}{4}\)
\(m=\large\frac{y-y_1}{x-x_1}\)
\(\large\frac{1}{4}=\frac{y-3}{x-7}\)
Can u do nw?
