Question

The equation of a line is x + 5y = 12. What is the y-intercept of the line? (Points : 1)

Answer 1

Option A: -12

Option B: 12

Option C: 5/12

Option D: 12/5

Answer 2

solve for y first.

Answer 3

\[x+5y=12\]
\[5y=12-x\]
\[y=\frac{12}{5}-\frac{x}{5}\]
move into y=mx+b form where b is your y-int
\[y=\frac{-x}{5}+\frac{12}{5} \]

Answer 4

\[b=\frac{12}{5}\]
