Question

What is the y coordinate when the x coordinate is -3 with the equation y=-8/5x+7/5

Answer 1

Given: A equation-

`y=-(8)/(5)x+(7)/(5)`

Required: To determine the y coordinate when the x coordinate is -3.

Explanation: The given equation is-

`y=-(8)/(5)x+(7)/(5)`

Substituting the value of x=-3 into the equation as-

`y=-(8)/(5)(-3)+(7)/(5)`

Further solving-

`\begin{gathered} y=(24)/(5)+(7)/(5) \\ =(31)/(5) \\ =6.2 \end{gathered}`

Final Answer: The value of the y coordinate is 6.2 or 31/5.
