<span>f(x)=3x−1
</span><span>domain is {-1, 0, 1}
3(-1) -1 = -4
3(0) - 1 = -1
3(1) - 1 = 2

The correct answer is letter C
The y-intercept will be 8
And then you work out the slope by replacing the c, y and the x in y=mx+c
The y and x will be any of the coordinates above
So it will be 0=m(8)+(8)
0=8m+8
So 8m=-8
Therefore m=-1
So the y-intercept is 8 and the slope is -1
