Answer:
1,500 dollars
Step-by-step explanation:
You would do 125 times 12 = 1,500
Use the point-slope form of the equation:-
y - y1 = m(x - x1) where m=slope and (x1,y1) is a point on the line
Here we have
y - 5 = -1/2(x - (-5))
y - 5 = -1/2(x + 5)
y = -1/2x - 5/2 + 5
y = -1/2x + 5/2
this can also be written as
2y = -x + 5
or in standard form it is x + 2y = 5
Answer:
slope of M'N' = 1
Explanation:
First, we will need to get the coordinates of points M' and N':
We are given that the dilation factor (k) is 0.8
Therefore:
For point M':
x coordinate of M' = k * x coordinate of M
x coordinate of M' = 0.8 * 2 = 1.6
y coordinate of M' = k * y coordinate of M
y coordinate of M' = 0.8 * 4 = 3.2
Therefore, coordinates of M' are (1.6 , 3.2)
For point N':
x coordinate of N' = k * x coordinate of N
x coordinate of N' = 0.8 * 3 = 2.4
y coordinate of N' = k * y coordinate of N
y coordinate of N' = 0.8 * 5 = 4
Therefore, coordinates of M' are (2.4 , 4)
Then, we can get the slope of M'N':
slope = (y2-y1) / (x2-x1)
For M'N':
slope = (3.2-4) / (1.6-2.4)
slope = 1
