ANSWER

y =  \frac{10}{3} x - 18

EXPLANATION

The given line has slope

m_{1} =  - 0.3

The line that is perpendicular to this line has a slope that is the negative reciprocal of -0.3

m_2 =  \frac{ - 1}{ - 0.3}

m_2 =  \frac{10}{ 3}

If the line e passes through (3,-8), then the equation is given by,

y -  - 8 =  \frac{10}{3} (x - 3)

y =  \frac{10}{3} x - 10 - 8

y =  \frac{10}{3} x - 18
