Question

complete ordered pairs for the equation, and then graph the equation. 4x + 5y = 20 (0,□) (type an integer or a fraction.)

Explanation:

Step1: Substitute x = 0 into the equation

We have the equation \(4x + 5y = 20\). Substitute \(x = 0\) into it, so we get \(4(0) + 5y = 20\).

Step2: Solve for y

Simplify the left - hand side of the equation: \(0+5y = 20\), which is \(5y=20\). Then divide both sides of the equation by 5, \(\frac{5y}{5}=\frac{20}{5}\), so \(y = 4\).

Answer:
