Answer: chord
Step-by-step explanation:
A chord is a straight line that's typically drawn from one particular edge of a circle to another.
In this case, the diameter is 14cm while the length of the line drawn is 11cm, therefore the diameter isn't a chord. It's not a radius as well as the diameter divided by 2 gives the radius which should be 7cm.
Therefore, it's a chord.
The slope of the linear function described in this problem is:
m = -3.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
In this problem, the line goes through points (5,3) and (8,-6). Considering that the slope is given by <u>change in y divided by change in x</u>, for this function, it is given by:
m = (-6 - 3)/(8 - 5) = -9/3 = -3
The slope of the linear function described in this problem is:
m = -3.
