Answer:
y=3(x+3)+3
Step-by-step explanation:
I think this is correct
y = 3x - 12
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3, thus
y = 3x + c ← is the partial equation
To find c substitute (3, - 3) into the partial equation
- 3 = 9 + c ⇒ c = - 3 - 9 = - 12
y = 3x - 12 ← equation of line
its mean marry me right here right now
the answer would be d
(8+12) is the sum
(8+12)10 would give you the answer of the sum of 8 and 12 times 10
