The answer would have to be
D
Answer:
![k=-\frac{1}{4}](https://tex.z-dn.net/?f=k%3D-%5Cfrac%7B1%7D%7B4%7D)
Step-by-step explanation:
we have
Line 1
![y=4x+1](https://tex.z-dn.net/?f=y%3D4x%2B1)
Equation in slope intercept form
The slope is equal to
![m_1=4](https://tex.z-dn.net/?f=m_1%3D4)
Line 2
![y-kx=10](https://tex.z-dn.net/?f=y-kx%3D10)
![y=kx+10](https://tex.z-dn.net/?f=y%3Dkx%2B10)
Equation in slope intercept form
The slope is equal to
![m_2=k](https://tex.z-dn.net/?f=m_2%3Dk)
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of the slopes is equal to -1)
so
![m_1*m_2=-1](https://tex.z-dn.net/?f=m_1%2Am_2%3D-1)
substitute
![(4)(k)=-1](https://tex.z-dn.net/?f=%284%29%28k%29%3D-1)
![k=-\frac{1}{4}](https://tex.z-dn.net/?f=k%3D-%5Cfrac%7B1%7D%7B4%7D)
Answer:
He will need to mow 5 lawns.
Answer:
-1/2
Step-by-step explanation:
We can find the slope if we are given two points
m = (y2-y1)/(x2-x1)
= (4-8)/(4 - -4)
= (4-8)/ (4+4)
= -4/8
= -1/2
