Question

What is the y-intercept of x + 4y = 7 ?

Answer 1

Given the following equation of the line:

$x+4y=7$

We will find the value of the y-intercept

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

so, substitute with x = 0, then solve for y

$\begin{gathered} 0+4y=7 \\ 4y=7 \\ y=\frac{7}{4} \end{gathered}$

so, the answer will be:

The y-intercept = 7/4

And the point of the y-intercept = (0, 7/4)
