Answer:
The answer is 3x+6
Step-by-step explanation:
You multiply what's on the outside of the parenthesis by everything on the inside, so you would do 3 times x and 3 times 2. They don't combine because they are like terms.
Standard form is x + y = number
The equation has a slope of 3 and a y intercept of -4 so the equation should be
y = 3x - 4
To get this in standard form you have to move the 3x to the other side.
y - 3x = -4
-3x + y = -4
The coefficient before x cannot be negative in standard form so you have to multiply the whole equation by -1.
3x - y = 4
Answer:
y = 3x - 17
Explanation:
3x - y = 17
-3x -3x

-y = -3x + 17

-1 -1. -1
y = 3x - 17
