Answer:
9
Step-by-step explanation:
X MULTIPLIED BY 3 EQUALS 9 SINCE X=3
Answer: y = 3x - 2
Step-by-step explanation:
slope intercept: y = mx + b, where m is the slope and b is the y-intercept.
Thus, because you already know the slope, you can simplify the equation to
y = 3x + b.
Then plug in the provided point to get, 4 = 3(2) + b
4 = 6 + b
-2 = b
Thus,
y = 3x - 2
