Answer:
B
Step-by-step explanation:
slope intercept form - y = mx + b
where m = slope and b = y intercept
first let's find the y intercept
The y intercept is the y value of the coordinate where the line passes the y axis
The line passes the y axis at (0,2)
The y value of this coordinate is 2 so b = 2
* plug in 2 *
now we have y = mx + 2
Now we want to find the slope.
slope is equal to the change in y over the change in x
As y goes up 3 x goes down 1
so slope = 3/-1 or -3
hence m = -3
* plug in -3 *
now we have y = -3x + 2
The answer is B
