1-119.

Find the equation of the line perpendicular to $3x − 7y = 42$ which passes through the point $\left(−3, − 8\right)$.

Solve for y to find the slope.

The perpendicular slope would be the negative reciprocal of the slope of the line.

Substitute the new slope and the point into the point-slope form of a line.

$-\frac{7}{3}$
