Answer: y= -1x+b, or -x+b
Step-by-step explanation:
The slope is 1 because you have to plug in the formula, y2-y1/x2-x1. -8-(-4)/5-1. This is equal to -4/4, which is -1.
Answer:
(26,-2)
Step-by-step explanation:
For any two points on coordinate plane (x1,y1) and ( x2,y2)
coordinate of midpoint is given by (x1+x2)/2 , (y1+y2)/2
Given
(x1,y1) = (-4,-8)
midpoint : (11,-5)
let other point be x2 and y2
therefor by using formula for midpoint coordinate given above we have
midpoint : (11,-5) = (-4+x2)/2 , (-8+y2)/2
Hence point
11 will be equivalent to (-4+x2)/2
11 = (-4+x2)/2
=> 11*2 = -4+x2
=>22 + 4 = x2
=>x2 = 26
similarly
-5 will be equal to (-8+y2)/2
-5 = (-8+y2)/2
=> -5*2 = -8+y2
=> -10 + 8 = y2
=> y2 = -2
Therefore coordinates of other point is (26,-2).
From the beginning we know we are dealing with two different rates. Distance is equal to (Speed X Time). We have two different speeds though. We will call the min speed = x and the max speed = y. With those two ideas in place we can make two equations for both Tony and Rae.
Tony:
2x+3.5y=355
Rae:
2x+3y=320
Now you can solve the equations by subtracting Rae's equation from Tony's
.5y=35 solve for y and you get 70
Now plug that y value back into either equation and you can solve for x. I'll use Rae's distance:
2x+3(70)=320
x=55
Answer:
so
slope is calculated this way:

let's calculate y init by:
3 = -3×2 + b
b = 9
so equation is:
y=-3x+9
