Question

Write the equation of a line that is perpendicular to the given line and that passes through the

Answer 1

Answer:

$y-9=-\frac{3}{7} (x+4)$

Step-by-step explanation:

Slopes are negative reciprocals when two lines are perpendicular

$m= - \frac {3}{7}$

Equation of straight line in point-slope form is given as

$y-y_1=m(x-x_2)$

Here $(x_1, y_1)= (-4, 9)$

$y-9=-\frac{3}{7} (x+4)$
