Answer:
x-coordinate = 0
Step-by-step explanation:
(-10,1) , (5,-5)
m = (y₂ - y₁)/(x₂ - x₁) = ( -5 - 1 ) / ( 5 - [-10] )
= -6 / ( 5 + 10)
= -6/15 = -2/5
y - y₁ = m (x - x₁)
y - 1 = (-2/5) ( x - [-10] )
y - 1 = (-2/5) ( x + 10 )
5 * (y -1) = -2 (x + 10)
5y - 5 = -2x -20
2x + 20 + 5y -5 = 0
2x + 5y + 15 = 0
Another point (a, -3) in on this line
2 * a + 5 * (-3) = -15
2a -15 = -15
2a = -15 +15
2a = 0
a = 0
x-coordinate = 0

Answer:
It is even because it is equal to 2(2n-3) so you can divide it by two and get (2n-3)
Step-by-step explanation:
Answer: 1
Anything to the 0 power is 1
Step-by-step explanation:
Answer:
(5,7)
Step-by-step explanation:
8x + 7y = 89
2x + 5y = 45
Multiply the second equation by 4
4(2x + 5y) = 45*4
8x +20y = 180
Subtract the first equation
8x +20y = 180
-8x -7y = -89
--------------------------
13y = 91
Divide each side by 13
13y/13 = 91/13
y =7
Now solve for x
2x+5y =45
2(x) +5(7) = 45
2x +35 = 45
Subtract 35 from each side
2x+35-35 = 45-35
2x =10
Divide each side by 2
2x/2 = 10/2
x=5
