Since the slope of a line is 
And 2 points of the line are given, (4,5) and (8,y) we can substitute those values into our equation.
Since the slope of the line is 3,
Multiplying both sides by 4 would give us:
y-5=12
y=17
Therefore the missing y value equals 17.

My "work" is to enter the equations into a graphing calculator and let it show me the answers--just as your "work" is to copy the question to Brainly.
The solutions are
(x, y) = (-0.5, 7.5)
(x, y) = (3, 25)
_____
When you equate the expressions for y, you get the quadratic
2x² -5x -3 = 0
(2x +1)(x -3) = 0
x = -1/2 or 3
y = 5(x +2) = 15/2 or 25
