5y = 40 + 4x

Now, divide both sides by 5 to get 'y' alone and get:

y = 4x/5 + 8

At this point, notice how the equation in the form of y = mx + b where 'm' represents the slope of the line.

Therefore, the slope of this line is 4/5.

Now i got it, since the question is -4x +5y=-40
so, y = 4/5 x - 8. i hope i am right...

Slope - intercept form of line equation is y = mx + b, where m is slope and b is y  - intercept.

The line equation is - 4x + 5y = - 40.

Add 4x to each side.

5y = 4x - 40

Divide each side by 5.

y = (4/5)x - 8.

The line equation in slope - intercept - form is y = (4/5)x - 8.
