Step-by-step explanation:
y=2x-5 is in y=mx+b
Where m = slope
![slope = m = 2](https://tex.z-dn.net/?f=slope%20%3D%20m%20%3D%202)
To find y-intercept :
![y = 2x - 5](https://tex.z-dn.net/?f=y%20%3D%202x%20-%205)
Let x =0
![y = 2(0) - 5 \\ y = 0 - 5 \\ y = - 5](https://tex.z-dn.net/?f=y%20%3D%202%280%29%20-%205%20%5C%5C%20y%20%3D%200%20-%205%20%5C%5C%20y%20%3D%20%20-%205)
Commutative property: a + b = b + a
3 + 5 + 7 = 3 + 7 + 5 = 10 + 5 = 15
Answer:
Bonsoir,
f'(-5)=-4/3
f'(-1) =3/4
Step-by-step explanation:
f'(-5) = ?
2 points : (-6,9) and (-3,5)
f'(-5)=(9-5)/(-6-(-3))=-4/3
f'(-1) = ?
2 points : (-3,5) and (1,8)
f'(-1)=(5-8)/(-3-1)=3/4
The lines are perpendicular
Answer:
When you subtract a negative number from another negative number then the second negative number will become positive and the minus sign will become an addition sign.
In this case:
-13 - (-13) = 0
-13 + 13 = 0
I hope I've helped explain this a little bit better to you.
