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-

$y=-\frac{8}{5}x+\frac{7}{5}$

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

Explanation: The given equation is-

$y=-\frac{8}{5}x+\frac{7}{5}$

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

$y=-\frac{8}{5}(-3)+\frac{7}{5}$

Further solving-

$\begin{gathered} y=\frac{24}{5}+\frac{7}{5} \\ =\frac{31}{5} \\ =6.2 \end{gathered}$

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