It is 5 and the y intercept is -2

5x + 2y = -10 general line equation form is: y= mx + c so 2y = -10 - 5x y = -2.5x - 5 m refers to gradient and c is offset on the y axis so gradient is -2.5 (gradient means slope)

The line described by the equation is a hyperbola and its gradient is different along its length. Its gradient is -10/(5x-3)2 except where x = 3/5 and the curve is not defined. The general form of a parallel curve is y = a + 2/[5(x + b) - 3] where a and b are constants.
It is: y = -1/5x-2
It is: 5
