Can someone solve point-slope lines and show work? I’m confused
1 answer:
Answer:
Option (2)
Step-by-step explanation:
Equation of a line passing through a point (x', y') and slope 'm' is given by,
y - y' = m(x - x')
From the question in the picture attached,
Slope of the line 'm' =
Line passes through a point (80, -71).
Equation of the line will be,
y + 71 =
y =
y =
Option (2) will be the answer.

Step-by-step explanation:
Area of a rhombus is the product of the length of the diagonals divided by two.
Length of one diagonal is 8 units and the other diagonal is 16 units
Area is given by
The area of the rhombus is
Another approach is the diagonals have created 4 triangles where the base and is height is either 4 units long or 8 units long so the area of the rhombus would be the area of the 4 triangles.
Answer:
14
Step-by-step explanation:
The inter-quartile range (IQR) is the difference between the third and first quartile. The data gathered is:
57, 59, 60, 62, 62, 63, 64, 68, 70, 70, 71, 71, 73, 79, 87, 89, 90
The data set has 17 values, the first quartile is the average between the 4th and 5th values, while the third quartile is the average between the 13th and 14th values:
The IQR is:
