Help me with algebra, its super important? ?

Two ships are sailing in the fog and are being monitored by tracing equipment. As they come into the observer's rectangular radar screen, one ship, the Rusty Tu, is at a point 900 mm to the right of the bottom left corner of the radar screen along the lower edge. The other ship, the Bucket of Bolts, is located at a point 100 mm above the lower left corner of that screen. One minute later, both ships' positions have changed. The rusty Tube has moved to a position on the screen 3 mm left and 2 mm above its previous position on the radar screen. Meanwhile, the Bucket of Bolts has moved to a position 4 mm right and 1 mm above its previous location on that screen.



Assume that both ships continue to move at a constant speed on their respective linear courses. Using graphs and equations find out if the two ship will collide.



How do i graph it on the computer? what do i need?!?!

and how do you do the work? i'm confused help me PLEASE

why and how do i make it equal each other?Help me with algebra, its super important? ?
We can treat the lower left corner of the screen as the origin of a graph and use the movement given as the slope, assuming that right is positive and left is negative.

So the slope of the Rusty Tube's Path is -2/3 and the slope of the Bucket of Bolts' path is 1/4.

Next,we find the y-intercepts. The Bucket of Bolts' intercept is easy to find, It's 100 mm. So the equation y= 1/4x+100

The Rusty Tube's equation is a little harder to find. Using point-slope form, we get

y- 0= (-2/3)(x- 900)

y=x+600

Graph both the equations or set them equal to to each other to see where and if they meet.
