Answer:
The equation of line is given as 
Step-by-step explanation:
Point on the line given :
We can find the slope of the line first from the given points.
Slope
= Undefined.
The slope of the line is undefined which means that the line is parallel to y-axis.
From the points known to us we can tell that the line passes through
∴ The equation of line is given as
Question should be sin 20 cos 10 + cos 20 sin 10
remember sin (a+b) = sin a cos b + cos a sin b ?
sin 20 cos 10 + cos 20 sin 10
= sin (20+10)
= sin 30
= 1/2
In order for two lines to be parallel, they must have the dame slope. In this case, it is 7/6. So the new line Will have the next form:
y = 7/6x + b
Now, assuming that the new line passes through the point (1,1):
1 = 7/6*1 + b
b = -0.17
Replacing b:
y = 7/6x - 0.17
X=1,y=1
1 )4x+2y=6
2 ) x -y=3
2(x2) ) 2x - 2y=6
