I'm trying to understand how to find the equation for a straight line where the angle is 30 deg and it passes through points (4,7)
Answer provided by our tutors
The equation of the line is:
y-y1= m(x-x1),
where (x1, y1) = (4, 7), that is x1 = 4, y1 = 7
and m = tan30
Now we plug the values into y-y1= m(x-x1):
is equation of the straight line where the angle is 30 deg and it passes through points (4,7).
If we graph the above equation we will see that it is indeed a straight line where the angle with x-axis is 30 deg and it passes through points (4,7):
