Step-by-step explanation:
i believe this is the answer but i am not 100% sure
Answer:
Step-by-step explanation:
4x - 2y = -5
-2y = -4x - 5
y = 2x + 5/2.....slope here is 2
-2x + 3y = -3
3y = 2x - 3
y = 2/3x - 1.....slope here is 2/3
NONE OF THE ABOVE.....they are not the same line....they are not parallel because they dont have the same slope....they are not perpendicular because they do not have negative reciprocal slopes
We can use the slope formula to find the slope between these two points:
![\frac{y.2 - y.1}{x.2 - x.1} = m](https://tex.z-dn.net/?f=%5Cfrac%7By.2%20-%20y.1%7D%7Bx.2%20-%20x.1%7D%20%3D%20m)
2 - 6 / -1 - 4
-4 / -5
Because there are two negatives, they cancel out.
The slope of the line between these two points is 4/5.
Answer:
45
Step-by step
What do we already know about the equation?
We know that they EACH bought a hockey puck($17) and 2 shirts
Half of 214 is 107. So they had to have spent 107 separately
So we make the equation and let s represent shirts
2s + 17 = 107
- 17 -17
2s= 90. DIVIDE by 2
s = 45
