Simplest way to do this?:
Slope intercept form is y = mx+b where m is the slope, and b is the y intercept.
That means that our equation HAS to have y = 3x as the first part because it's the slope.
Now to find 'b'.
To find b there's two methods, and I'll be telling you both.
You can either plug (-1,-8) into the equation of y = 3x + b, or just add 3 to the -8 because you're basically trying to find the y intercept, which is at x = 0, which is just 1 unit away from -1,-8. And because you're increasing by intervals of 3 between each x unit, you just add 3 to the y value, and you have -5.
If you plug it in: -8 = -3 +b you'll get the same thing. b = -5
In this case answer choices A and D would be right.
Hope I helped :)
