Answer 1

Based on the graph, an equation in standard form for this line is -x + y = 0.

In Mathematics and Euclidean Geometry, the standard form of the equation of a straight line is given by this mathematical equation;

Ax + By = C

Where:

• A, B, and C represents a constant or numerical value.
• x and y are variables.

In Mathematics and Geometry, a proportional relationship is a type of relationship that produces equivalent ratios and it can be represented by the following mathematical equation:

y = mx

Where:

• y represents the y-variable​.
• x represents the x-variable.
• m is the constant of proportionality.

For the constant of proportionality, we have;

k = y/x

k = 1/1 = 2/2 = 3/3

k = 1

Therefore, the equation in standard form can be written as follows;

y = x

-x + y = 0
