Answer:
Step-by-step explanation:
To write this equation we first need to know what the standard form is. Standard form of a line is written as . To get this, we first need to put the equation into point slope form or
where
is slope and
is a point on the graph. Using the information we know we can make the equation
.
Now that we have point slope form we need to convert it. To do this we need to first get rid of the parenthesis by distribution. This will give us
Next, we know we need to get and
on the same side of the equal sign. We do this by subtracting 3x on both sides to get
Finally, we can subtract 2 on both sides to put the equation into standard form. This will give us
