Answer:
3rd option,
Step-by-step explanation:
To find out which option is correct, we can write the equation in point-slope form ourselves.
Use the point-slope formula to write the equation in point-slope form. Substitute the
,
, and
for real values.
Since represents the slope, substitute
in its place. Since
and
represent the x and y values of a point the line intersects, substitute the x and y values of (5,1) into the formula as well. Substitute 5 for
and 1 for
. This gives the following equation:
Answer:
