Question

Find the y-intercept of the following line: 2x -4y = 8

Answer 1

Given the equation:

$2x-4y=8$

The given equation represents a line, we will find the y-intercept

The y-intercept is the value of y when x = 0

so, we will substitute with x = 0

$\begin{gathered} 2\cdot0-4y=8 \\ -4y=8 \\ y=\frac{8}{-4}=-2 \end{gathered}$

So, the answer will be the y-intercept = -2
