The equation of a line is y=-1/4x-7, (option 1)
<h3>
What is the equation of a line? </h3>
A straight line's general equation is y = mx + c, where m denotes the gradient and y = c denotes the point at which the line crosses the y-axis.
<h3>
How do you find the equation of a line?</h3>
Write the equation in the form y = mx + b to find the slope m and the y-intercept. This will allow you to graph the equation using the slope and y-intercept.
Given:-
Equation of the line is y=4x+8
The point through which the line passes (-8,4).
here the slope of the line is m1=4
To find the perpendicular line we know the formula
m1*m2=-1
By putting the value of m1 we get m2= -1/4
By using the one-point formula of the line we have
=>(y-y1)=m2*(x-x1)
By putting the values of y1 and x1 we get
(y1,x1)=(-8,4)
=>(y+8)=-0.25*(x-4)
y+0.25x+7=0
Hence the desired equation of the line is y=-1/4x-7

(6x9)/2=27..........................
The correct answer is C and E
Explain
A. 8x+4x=0
Now simply it
12x = 0
Now divide by 12 on both both side
X= 0
So this equation has the solution x= 0
B. 6x+2 = 4x+2+2x
Now both sides
6x+2=6x+2
Now simply by 6x+2 both sides
X= 0
So this equation has infinity solution
C. 4x-8x-3=6-4x
Now simply both sides
-4x-3=6-4x
Now simply
-3x=6
This equation have no solution
D. 5x+1 =1-5x
Now add 5x-1 on both sides
10=0
Now divide by 10
X= 0
This equation have solution x= 0
E. 12x-3-5x = 9+7x-6
Now simply both sides
7x-3= 7x+3
And subtract 7x from both sides
-3 = 3
So the equation has no solution
I hope this help you :D
Good luck
The value of x is 84 degrees
