Which function rule (equation) describes the line that passes through points (2, 5) and (0, 9)?
A. y = -2x + 9
B. y = 2x + 9
C. y = 9x + 5
D. y = -x + 9
Since (0,9) is on the line, you know that it will be "+9" in the function
So, what + 9 = 5?
-4, right?
So, what times 2 = -4?
-2, right?
y = -2x+9
