2 answers:
(?,6) is on the line 2x-7y = 0.
We are given only the y coordinate half part here which is 6.
Since this point lies on the given line, so if we plug value of y in the given equation, we can easily find value of x by solving the equation.
So plugging y=6 in the given equation,
Adding 42 on the right side,
diving right side by 2
x=21
Answer:
So the half part of coordinate that is x part is 21.
Complete coordinate is (21,6)

Step-by-step explanation:
y=x+6.......(1)
y=-3X-6....(2)
from eq (1), we get,
x=y-6....(3)
sub eq (3) in eq (2), we get
y= -3(y-6)-6
y= -3y+18-6
y+3y-12=0
4y=12
y=3
sub value of y in eq (3)
x=3-6
x=-3
Answer:
d = 9
Step-by-step explanation:
Calculate the slope m of line AB and equate the result to 3
m =
with (x₁, y₁ ) = A(4, 6) and (x₂, y₂ ) = B(d, 21)
m = =
= 3 ( multiply both sides by d - 4 )
15 = 3(d - 4), that is
15 = 3d - 12 ( add 12 to both sides )
27 = 3d ( divide both sides by 3 )
9 = d
