Answer:
Yes, Cora is correct.
The equation of line with point (2,6) and slope of line (-1/3)
is x + 3y - 20 = 0
Step-by-step explanation:
Yes, the equation of a line can be written using a point and a slope of the line equation.
Cora has used the POINT SLOPE FORMULA, to represent the line equation.
In <u>Point Slope formula</u>:
The equation with slope m and points (x0,y0) can be written as:
(y-y0) =m (x-x0)
Here, the point (x0,y0) = (2,6)
and slope m = (-1/3)
So, the equation can be written as:
Hence, the equation of line with point (2,6) and slope of line (-1/3)
is x + 3y - 20 = 0
