Which equation represents a line that passes through (5,1) and has a slope of 1/2?

Answer:
C
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
here m = [tex]\frac{1}{2}[/tex] and (a, b) = (5, 1), hence
y - 1 = [tex]\frac{1}{2}[/tex](x - 5) → C
For this case we must find the equation of the line that passes through point (5,1) and has slope [tex]m = \frac {1} {2}[/tex]
By definition, the equation of the point-slope line is given by:
[tex](y-y0) = m (x-x0)[/tex]
We have the point:
[tex](x0, y0) = (5,1)[/tex]
Substituting:
[tex](y-1) = \frac {1} {2} (x-5)[/tex]
Answer:
[tex](y-1) = \frac {1} {2} (x-5)[/tex]
