Question

Determine the y-interceptfor the following equation:7.2y + 4.5x = 72Y intercept:

Answer 1

The given expression is

`7.2y+4.5x=72`

To find the y-intercept, we have to solve the equation for y.

`\begin{gathered} 7.2y=72-4.5x \\ y=(72-4.5x)/(7.2) \\ y=10-0.625x \end{gathered}`

Remember that the y-intercept is the independent term.

Therefore, the y-intercept is 10, or the point (0, 10).
