The equation of the function shown in the graph provided is y = - 3x - 6.
How to determine the equation of the line shown in the graph?
The equation of the function shown in the graph provided is determined as follows;
The general equation of a line is given as;
y = mx + c
where;
- m is the slope of the line
- c is the y - intercept of the line
The slope of the line is calculated as follows;
m = Δ y / Δ x
m = ( - 6 - 0 ) / (0 - - 2)
m = - 6 / 2
m = -3
The y - intercept of the line = -6
The equation of the line becomes;
y = - 3x - 6
