Answer:
the equation of the line is 7x + y = 0 .
Step-by-step explanation:
in the standard form of the line that is Ax +By = C we can write it in the form of
By = C - Ax
which is in the form of 
where m is the slope of the line and c is y intercept made by the line.
comparing and
we get that 
and 
since it is given that slope of the line is -7 therefore m = -7 and c = 0
therefore 
and 
therefore C = 0 , A = 7 and B = 1
therefore the equation becomes 7x + y = 0
Answer:
-3+6y = 9x
6y = 9x+3
y = 9/6x+3/6
y = 3/2x+1/2 ⇒ slope-intercept form
Answer: SOLUTION: find three cosecutive odd integers such that the sum of the least and greatest is 78. Let x, x+2, x+4 b the 3 consecutive odd integers. 37, 39, 41.
Step-by-step explanation: look above lol hope this helps u gud luk
The length of the semi-major axis of the ellipse is 7.
What is the semi-major axis of an ellipse?
The semi-major axis of an ellipse is the half of the longest diameter passing through its vertex and focus.
The general equation of an ellipse is :
⇒ x²/a²+y²/b²=1, where a is the semi-major axis and b, is the semi-minor axis
x²/49+y²/36=1
x²/(7²)+y²/(6²)=1
x²/a²+y²/b²=1
a=7
