Answer:
y=6
Step-by-step explanation:
edge2020
comparing the relation given
thus y= -2x +1 to the general equation of a line
where y= mx + c
where m is the gradient and c is the intercept on the y-axis.
from the question, the gradient is -2 and since the line is perpendicular, the gradient is given as

so substituting the value of m in to the equation

=

as the gradient
equation of line is given by
y - y1 = m( x-x1)
from the question y1= -2 and x1=1
substitute them
y-(-2) = 1/2 (x -1)
y+2 =1/2 (x-1)
multiplying through by 2
2 (y+2) = x-1
2y +4 = x-1
2y =x-1-4
2y =x-5
x -2y -5 = 0
therefore the equation for the line is x-2y -5=0
Answer: 3rd option : Angle 2 and 7
Step-by-step explanation:
Alternate exterior angles are located on the outside of the parallel line on opposite sides.
Therefore, the alternate exetrior angles are 1 and 8 and 2 and 7.
Since there is no option for angle 1 and 8, the correct answer is the 3rd option --> Angle 2 and 7.
12% bc the difference is 21 and do 21 divided by 175 trust me
Yes!
This would be in-fact a linear equation!
<h3>How?</h3>
This equation is set up in y=mx+b form, therefore we know it is a linear equation.
<h3>Example of a linear equation:</h3>
y=12x+2
The 12 is the mx in the equation.
And the 2 is the B in the equation! :)
That is how we solve that.
Any questions?
Have a great day!
