Answer:
y = 3x - 3
Explanation:
y = mx + b
m = slope
slope = y2 - y1/x2 - x1
slope = 6 - 3/3 - 2
slope = 3/1
slope = 3
y = 3x + b
b = y-intercept
y-intercept is y when x = 0
rise over run
If slope = 3/1, then subtract 3 from y and 1 from x until x = 0
(2, 3) = 3/2
3 - 3/2 - 1 = 0/1 = (1, 0)
0 - 3/1- 1 = -3/0 = (0, -3)
x = 0
y-intercept = -3
y = 3x + - 3
negative + positive = negative
y = 3x - 3
