Answer:
C, F, D
Step-by-step explanation:
For each side of each triangle, think of the side as the hypotenuse of a right triangle. Then use the Pythagorean theorem to find the length of the hypotenuse, which is the side of the triangle.
Left problem:
From point C to point A, go 2 left and 7 up.
From point A to point B, go 5 right and 1 down.
From point B to point C, go 6 down and 3 left.
Perimeter = 7.3 + 5.1 + 6.7 = 19.1
Do the same for the other triangles.
Middle problem:
From point F to point D, go 2 left and 7 up.
From point D to point E, go 7 right and 2 down.
From point E to point F, go 5 down and 5 left.
Perimeter = 7.3 + 7.3 + 7.1 = 21.7
Right problem:
From point L to point J, go 7 left and 1 up.
From point J to point K, go 4 up and 5 right.
From point K to point L, go 2 right and 5 down.
Perimeter = 7.1 + 6.4 + 5.4 = 18.9
The equation of the line that passes through the point (-6,3) and has a slope of -4/3 is y=(-4/3)x-5.
<h3>What is the equation of a line?</h3>A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is constant.
Given the slope of the line is -4/3, also, the line passes through the point (-6,3). Therefore, when the values are substituted in the general equation of a line to get the value of the constant, we will get,
y = mx + c
3 = (-4/3)(-6)+c
3 = 8 + c
c = -5
Thus, the equation can be written as y=(-4/3)x-5.
Hence, the equation of the line that passes through the point (-6,3) and has a slope of -4/3 is y=(-4/3)x-5.
