y = (-51x)/5 -15036/5

Explanation:

Usung the formula y-y_1 = m(x-x_1)
Considering
(99, -40) and (104, -91)
(x_1, y_1) and (x_2, y_2)

m (gradient) = (y_2-y_1)/(x_2-x_1)

m = (-91-(-40))/(104-99)

m = -51/5

y-(-40) = -51/5(x-99)

y-(-40) = (-51x)/5+5049/5

y = (-51x)/5+5049/5-4017

y = (-51x)/5 -15036/5

This is the equation of the line
