Choice 2 is correct
Answer:
28 units.
Step-by-step explanation:
The distance between two given points () and () is given by the formula
So, the distance between points (-2,-4) and (-1,6) is
units.
Now, the distance between points (-1,6) and (3,8) is
units
Again, the distance between the points (-2,-4) and (3,8) is
units.
Therefore,the perimeter of the triangle is (10.05 + 4.47 + 13) = 27.52 ≈ 28 units. (Approximate)
We begin with the <span> Turner Middle School:
Ratio of students to teachers: </span>
Green Middle School:
Ratio of students to teachers:
Let check that we cannot form a proportion:
The two ratios are not equals so we cannot form a proportion.
Let x be the number of <span>teachers that Green have to hire in order to make the two ratios equal. We get the equation:

Using the point-slope equation, the equations that represent the data are:
y - 6 = -1.25(x + 2)
y -3.5 = -1.25x
<h3>What is the Point-Slope Equation?</h3>
Given a point (a, b) and slope (m), the point-slope equation is expressed as, y - b = m(x - a).
Find the slope (m) using two pairs from the table of values say, (-2, 6) and (2, 1):
Slope (m) = change in y / change in x = (6 - 1)/(-2 - 2) = 5/-4 = -1.25
Using the point, (a, b) = (-2, 6) and m = -1.25, plug the values into y - b = m(x - a):
y - 6 = -1.25(x - (-2))
y - 6 = -1.25(x + 2)
This cam be rewritten as:
y - 6 = -1.25x - 2.5
y - 6 + 2.5 = -1.25x
y -3.5 = -1.25x
The equations that represent the data in the table are:
y - 6 = -1.25(x + 2)
y -3.5 = -1.25x
