find the equation of the straight line which passes through the point (-2,4) and is parallel to the line y=2x +5.
1. find the equation of the straight line which passes through the point (-2,4) and is parallel to the line y=2x +5.
y = 2x + 5
m = 2
y - b = m(x - a)
y - 4 = 2(x -(-2))
y - 4 = 2(x + 2)
y - 4 = 2x + 4
y = 2x + 4 + 4
y = 2x + 8
2. Determine the equation of straight line: passing through (3,6) and parallel to the line 2y + 2x = 3

3. The line equation that is parallel to the line 3x-5y+4 = 0 and through the point (-10,2) is
Jawaban:
*
gradien sejajar
m2 = m1
*
mencari gradien
a/b
a = angka didepan x
b = angka didepan y
*
contoh
by = ax + c
maka gradiennya
a/b
*
tentukan m1 dari persamaan 3x - 5y + 4 = 0
ubah kedalam persamaan by = ax + c
3x - 5y + 4 = 0
-5y = -3x - 4
maka
gradiennya = -3/-5 = 3/5
*
tentukan m2
ingat m2 = m1 maka m2 = 3/5
*
rumus persamaan garis dengan gradien dan 2 buah titik
(y - y1) = m(x - x1)
*
maka persamaan garis dengan gradien 3/5 dan titik (-10 , 2)
x = -10 , y = 2
(y - y1) = m(x - x1)
(y - 2) = 3/5 (x - (-10))
y - 2 = 3/5 (x + 10)
y - 2 = 3/5 x + 6
y = 3/5 x + 6 + 2
y = 3/5 x + 8

4. 1. From the numbers in the text, we knowthat ....A. the equatorial line is longer than theaxis lineB. the equatorial line is shorter than theaxis linethe equatorial line and the axis lineare of the same lengthD. the axis line is longer than theequatorial lineC.
you have to put the text so we can anwers those questions..
5. the gradient of the line perpendicular to line a is ...
Jawaban:
Perpendicular Lines (HIGHER TIER)
Penjelasan:
Two lines are perpendicular if one is at right angles to another- in other words, if the two lines cross and the angle between the lines is 90 degrees. If two lines are perpendicular, then their gradients will multiply together to give -1

6. find the equation of the line parallel to the line y=2x+4 passing through the point (6,2)
Penjelasan:
y - y1 = m2(x - x1) y - 2 = 2(x - 6)y - 2 = 2x - 12y = 2x - 12 + 2y = 2x - 107. find the equation of the line through the -5.6 point and perpendicular to the line 3x-2y + 2 = 0
3x-2y+2=0
y=mx
-2y=-3x..
y=3/2x
m=3/2
3/2.m2=-1
m2=-2/3
y-y1=m(x-x1)
y-6=-2/3(x+2)
----------------------x3
3y-18=-2(x+2)
3y-18=-2x-4
2x+3y=-4+18
2x+3y=14
8. which line is not diameter? Explain
Jawab:
Line AO and Line BO
Penjelasan dengan langkah-langkah:
a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle.
Line AO and BO is a line segment with one end at the center of the circle, therefore it is a radius

11. a line cuts x-axis at (-5,0) and y-axis at (0,7).find1)the equation of this line2)the equation of another line parallel to this line and passes through point (10,5)
(y - y1) / (y2 -y1) = (x - x1) / (x2 - x 1)
(y - 0) / (7 - 0) = (x - -5) / (0 - - 5)
y / 7 = (x +5) / (0 + 5)
y / 7 = (x + 5) / 5
5y = 7 (x + 5)
5y = 7x + 35
y = (7/5)x + 7. => m = 7/5
2) y - y1 = m (x - x1)
y - 5 = 7/5 ( x - 10
y - 5== (7/5)x - 7
y = (7/5)x - 2

13. Find the equation of the line passing through the point (2,-5) and parallel to the line 5x + 7y = 46.tolong dibantu secepatnya, dan yang benermakasii
question:
Tentukan persamaan garis yang melalui titik (2,-5) dan sejajar dengan garis 5x + 7y = 46.
answer:
y -y1 =m(x - x1)
y -(-5)=(-5/7)(x -2)
y +5=(-5(x-2))/7
7(y +5)=-5x +10
7y+45=-5x +10
45-10=-5x -7y
-5x -7y=35

17. 13. In Diagram 3, the FG is parallel to the line Hl. 3x Find the value of x. G 2x
Based on the information provided, it is not possible to determine the value of x without additional information. The diagram and the statement "FG is parallel to the line Hl" do not provide enough information to solve for x. To find the value of x, we would need to know more about the size of the angles and the lengths of the lines in the diagram.
