I believe 11 centimeters is the answer.
The line crosses (1/2,0) and (0,4/7)
Let m be the slope of this line
● m = [0-(4/7)]/[(1/2)-0)]
● m = (-4/7)/(1/2)
● m = (-4×2)/7
● m = -8/7
So the slope of this line is -8/7
There is no attached picture, but I guess it is like the one I attached.
If so, the first thing is finding the side measure:

Now, radius is half this measure: 15 in.
And circle area is:
Answer:
a. 3
b. 6
and i got the last answer as 11
I am not too sure about the last one, sorry. Hope this helped!
Step-by-step explanation:
Answer:
y= -2/3x - 2
Step-by-step explanation:
So, the easiest thing to find first is your y-intercept, or the point in which the line crosses the y-axis. In this graph, the y intercept would be -2. Now, we can find the slope. One way to find the slope is to start at a point and count the numbers it rises and then the number it runs. Or, you can choose two points, like (0,-2) and (3,-4) and use the formula for slope, (y2-y1) / (x2-x1). Plug those numbers in and get (-4 minus -2)/ (3 minus 0), which would give you -2/3.
