Question

I need to know the x and y intercept of this equation:
y=5x-1

Answer 1

To find the x intercept, set y equal to 0:
\[\large 0=5x-1 \]
Solve:
\[\large 1=5x \]
\[\large \frac{1}{5}=x \]
So your x intercept is \(\large \color{red}{(\frac{1}{5}, 0)} \)
To find the y intercept, set x=0:
\[\large y=5(0)-1 \]
giving you:
\[\large y=-1\]
So your x intercept would be \(\large \color{yellow}{(0, -1)}\)
