Answer:
The answer is: y = 3x - 2
Step-by-step explanation:
Use the slope equation to find the slope:
m = (y - y1) / (x - x1)
m = (4 - 10) / (2 - 4)
m = -6 / -2 = 3
Now use the point slope form of the equation with one point, will use (2, 4)
y - y1 = m(x - x1)
y - 4 = 3(x - 2)
y - 4 = 3x - 6
y = 3x - 2
Proof:
f(4) = 3(4) - 2
= 12 - 2 = 10, giving (4, 10)
