The equation of the tangent line can be found using slope formula and fact that slope = dy/dx.
where (x0,y0) is point A ---> (0,-1)
Then rearrange equation into slope-intercept form:
Finally sub in x=0 into dy/dx to get slope at the point (0,-1)
I think its 40 over 81, 40/81
Answer:
x+2y=6
Subtract 2y from both sides.
x=6−2y
Step-by-step explanation:
x=6-2y
