From one point to the next x increases by 4, while y increases by 2.
So, it's a linear equation/relation/function, with a slope of for y as a function of x.
The equation would be .
Substituting the coordinates of point (4, 5)
--> --> -->
So the equation could be or any of the infinity of equivalent equations,
like (obtained by multiplying both sides times 2).
or , or , or .
