That's a line:
g(x)=0.5*x-1, pick up some x, and get the y.
For instace: x=0, g(0)=y=-1, x=2, g(2)=y=0.
Two pints are enough for a line.
13 i think idk i’m pretty sure it’s 13 ya i think it is
The correct answer is A.) f(x)=

x+1
This is because using slope intercept form (y=mx+b), we can solve.
m = slope
b= y-intercept
If you look at the graph, you can see the line crosses they y-axis at 1.
And if you follow the line using rise over run, you find that it is 1/3.
But because it is a negative line, it makes the slope negative.
Hope this helps!
Answer:
180-degree angle
This is not a 90-degree angle because if it were to be, then it would be AB, which is not what we are going for, which leaves BC as 180 degrees (if you see it on a protractor)
Answer:
perpendicular lines
