Gerry and Alain run around a running track. To run around the track once

Gerry always takes 90 seconds.
Alain always takes 105 seconds.

They start together at the same point. After how many minutes are they next together at that point?

hello non compreis syo ti kases dsl mais nno

y=1.8x-9

Step-by-step explanation:

if they are intercepts so the x/y will be zero, so in y intetceot the x is zero, and in the x itercept the y is zero.

0,-9

5,0

we calculate the slooe / rise

-9-0/0-5 = 1.8

we then use this formula

y-y1=rise(x-x1)

y-0=1.8(x-5)

y=1.8x-9
