Draw horizontal and vertical lines on a picture where the gap between the lines increases linearly. Start at 10, then 12, then 14.

Question

The important part here is to make sure the value you add on by is increasing by two every time.

Answer 1

```
def lineExample2 ():
img = makePicture(pickAFile()) verticalLines(img)
horizontalLines(img)
show(img)
return img

def horizontalLines(src):
increase = 0
multi = 0
for x in range(0,getHeight(src),2):
for y in range(0,getWidth(src)):
if x==increase:
setColor(getPixel(src,y,(x)),black)
if x==increase:
increase = increase+10+multi*2
multi = multi+1


def verticalLines(src):
increase = 0
multi = 0
for x in range(0,getWidth(src)):
for y in range(0,getHeight(src)):
if x==increase:
setColor(getPixel(src,(x),y),black)
if x==increase:
increase = increase+10+multi*2
multi = multi+1
```
