A line with slope m and y-intercept c passes through which fixed point?
AOne and c
BOne and m
CZero and c
DZero and m
Answer & Solution
Correct answer: C. Zero and c
1. The y-intercept is where the line crosses the vertical axis.
2. At that crossing the x coordinate is nothing.
3. So the coordinates of that point are zero and c.
4. Applying the point-slope form there gives y equals mx plus c.
