Question

Which coordinate point represents the y-intercept of the equation 3x + y = 18?

Answer 1

write the equation in the slope-intercept form

`\begin{gathered} 3x+2y=18 \\ 2y=-3x+18 \\ y=-(3)/(2)x+9 \end{gathered}`

according to this the y intercept of the equation is 9 that written as a coordinate is the point (0,9)
