Y=2x-4
X+2y=10
Put y into the x equation
X+2(2x-4) =10
Expand and simplify
X+4x-8=10
5x-8 =10
5x=10+8
5x=18
X=18/5
Insert x into the original equation to get y
Y=2x-4
Y=2(18/5)-4
Y=16/5
It is 160000 because 8*2 is 16 just add 0000 after the 16
Answer:
y=4x and x+4y=12 are perpendicular because they have opposite reciprocal slopes
Step-by-step explanation:
y=4x slope is 4
x+4y=12 slope is -1/4
Answer:
The equation of line with given points and perpendicular to y-axis is
y = - 7
Step-by-step explanation:
Given as :
The given points as ( - 10 , - 7)
The equation of line is Y = mX + c
So The line will satisfy given points
Or, - 7 = m ( -10 ) + c
Now This line is perpendicular to y- axis
∴ The slop of line perpendicular to y axis is 0
So, - 7= 0 + c
or, c = - 7
∴ Equation of line is y = 0 + c
Or, y = - 7
Hence The equation of line with given points and perpendicular to y-axis is y = - 7 Answer
