Slope: (y2-y1)/(x2-x1)
(12-2)/(2-7) = 10/-5 = -2
Y = -2x + b
2 = -2(7) + b, b = 16
Y = -2x + 16
Answer:
Step-by-step explanation:
The distance formula is d=![\sqrt{(x2-x1)^{2} +[tex]\sqrt{(0-0)^{2} + (12-3)^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B%28x2-x1%29%5E%7B2%7D%20%2B%5Btex%5D%5Csqrt%7B%280-0%29%5E%7B2%7D%20%2B%20%2812-3%29%5E%7B2%7D%7D)


= 9
M= 1/2
to find this you plug in the points into the the formula m=y2-y1 / x2-x1
m=3-6 / -4-2
m=-3 / -6
this simplifies to m=1/2
Answer:
x is 7, y is -1
Step-by-step explanation:
x+7y=0
2x-8y=22 -> divide both sides by -2
x+7y=0
-x+4y=-11
Eliminate one of the equations by adding the equations.
11y=-11
y=-1
Substitue the value of y into te equation
x+7*(-1)=0
x=7
