The equation of this straight line is equal to y = 3x.
<h3>How to calculate the slope of a line?</h3>In order to determine the equation of this line, we would first of all calculate its slope. Mathematically, the slope of any straight line can be calculated by using this formula;
By critically observing the given graph, we can logically deduce the following points:
Point (x, y) = (0, 0)
Point (x, y) = (3, 9)
Substituting the given points into the formula, we have;
Slope = (9 - 0)/(3 - 0)
Slope = 9/3
Slope = 3
Mathematically, the standard form of the equation of a straight line is given by;
y = mx + c
<u>Where:</u>
- m represents the slope.
- x and y are the points.
- c represents the intercept.
<u>Note:</u> The y-intercept of this graph is equal to zero (0).
Substituting the parameters into the equation of a straight line, we have;
y = 3x + 0
y = 3x
