You have the slope and you have two points, so you can use the slope equation to find x.
So your answer is x = 8.
The slope is 3/4
you just count how many it goes up before it goes over to a whole unit
So to do this one, you have to do the problem backwards!
The equation looks like this with everything plugged in:
272.2 = 2(3.14)r
You are looking for r, so start dividing
272.2 = 2(3.14)r
136.1 = (3.14)r
43.3 = r
Therefore the radius is about 43.3 in.
I hope I helped!
Answer:
the slope of the line is 4
m = 4
y-intercept is -8
y = 4(0) - 8 = 0 - 8 = -8
