Question

Indicate, in standard form, the equation or inequality that is shown by the graph.

Answer 1

Answer:

The equation is  y = -x + 4

Step-by-step explanation:

This is a very trivial exercise:

The general equation of a line is given by:

y - y₁ = m(x - x₁)

where m = slope of the linear graph

From the given graph, it can be observed that the coordinate (x₁, y₁) and (x₂, y₂) are (0, 4) and (4, 0)

The slope, m = (y₂ - y₁)/(x₂ - x₁)

m = (0 - 4)/(4 - 0)

m = -4/4

m = -1

Substituting the values of (x₁, y₁) = (0, 4) and m = -1 into the general equation:

y - y₁ = m(x - x₁)

y - 4 = -1 (x - 0)

y - 4 = -x

y = -x + 4
