write an equation for each line
The line y = 2.5x translated up 4 units

y=2.5x is a line with a slope of 2.5 znd a y-intercept of 0.
So when you translate the line up 4 units, simply add 4 to the
y-intercept and get 0+4=4.
The new equation then is y=2.5x+4

Adding 4 to the x, as in y = 2.5(x+4) will move it 4 units to the left. Adding 4 at the end, though, as in y = 2.5x + 4, willo move it 4 units up.

y = 2.5x + 4
As a quick check, substitute 0 for x in both equations. You get y = 0 and y = 4, meaning that the second point is 4 points above the first point.

y=2.5x has an intercept at y=0. move it up 4, the intercept will be at y=4 so
y=2.5x+4

y=2.5x
when translated to 4 units
x=X+4
y=Y
then
Y=2.5(X+4)
Y=2.5X+10
