Answer:
In step 2, she didn’t use an x and y from the same coordinate pair
Step-by-step explanation:
see the attached figure to better understand the problem
we have the points (5, 1) and (3, 5)
step 1
Find the slope
The formula to calculate the slope between two points is equal to
substitute
step 2
The equation of the line in point slope form is

take the point (3,5)
substitute



step 3

therefore
In step 2, she didn’t use an x and y from the same coordinate pair
The answer is 15.
hope this helps!

Answer:
x = 12
Step-by-step explanation:
The right triangles are all similar, so the ratios of long to short ides are the same:
x/6 = 6/3
x = 6(6/3) . . . multiply by 6
x = 12
Answer:
y=3/4x+2
Step-by-step explanation:
2 is the y intercept.
Go up 3 right 4 to reach a even point.
Answer:
300tan43 - 300tan40
Step-by-step explanation:
Use tangent to find the height of the building:
tan40 = b/300
b = 300tan40
The use tangent to find the height to the top of the antenna:
tan43 = a/300
a = 300tan43
The antenna height = a - b
