Question

Question 4 The value of the x-intercept for the graph of 4x - 5y = 40 is

Answer 1

The x-intercept ocurrs at y=0. Then, by substituting y=0 in our expression, we get

`4x-5(0)=40`

which gives

`4x=40`

by moving the coefficient of x to the right hand side, we have

`\begin{gathered} x=(40)/(4) \\ x=10 \end{gathered}`

then, the answer is x=10, which corresponds to the first option
