Answer:
y = 3x -3
Explanation:
Find the slope first
Givens
y2 = 3
y1 = - 3
x2 = 3
x1 = 1
Equation
m= (y2 - y1)/(x2 - x1)
Solution
m = (3 - - 3) / (3 - 1)
m = (3 + 3) / 2
m = 3
Find the y intercept next
Use either point to find the y intercept
y = 3x + b
x = 3
y = 3
y = 3*3 + b
3 = 6 + b
-3 = b
Answer
y = 3x - 3
