Question 164266
Slope-intercept form is y=mx+b

If your slope is 2 first substitute this into the form for the m so you get
y = 2x+b

now you know the values of x and y from the point you are given (3,2) 

We can substitute 3 for x and 2 for y so we have 

2 = 2(3) + b.

We now need to find what the value of b is so we solve
2= 2(3)+ b or 
2 = 6 + b or 
-4 = b.

we can substitute this value of b into our equation to get

y = 2x -4
