Which is the equation of the given line in slope-intercept form?
a. y = 3x +2
b. y = 3x - 2
c. y = - 3x + 2
d. y = - 1/3x + 2

The formula for slope-intercept form is y = mx + b.
M being the slope and B being the y-intercept.
The first thing I would do is find the slope. (y2-y1/x2-x1)
The slope is -3/1 or -3.
So now the equation looks like this:
y = -3x + b
Now to find the b.
The y-intercept is the value of why when x is zero. In this case it is 2.
So your answer is y = -3x + 2.
Hope this helps!
