Wolfgang and Heinrich worked as electricians at $14 and $12 per hour respectively. One month Wolfgang worked 10 hours more than
Licemer1 [7]

Let us say that:

x = hours worked by Wolfgang

y = hours worked by Heinrich

 

So that:

x = y + 10

14 x + 12 y = 3520

 

By combining the two equations:

14 (y + 10) + 12 y = 3520

14 y + 140 + 12 y = 3520

26 y = 3380

y = 130 hours

x = y + 10 = 140 hours

 

<span>So Wolfgang worked 140 hours while Heinrich worked 130 hours.</span>

What is the y-intercept of the line whose equation is y=-x-2?
dalvyx [7]

If we have an equation of the form y = mx +b then the y-intercept is b.

So now here we have y =-x - 2. Therefore b = -2 and we conclude the y-intercept is -2.
