The equation of this straight line is y = 50x + 100.
<h3>What is a linear function?</h3>A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.
<h3>How to determine the equation?</h3>In order to determine the equation from this graph of a linear equation, we would find the slope of the straight line by using this formula as follows:
Slope, m = 100/2
Slope, m = 50.
Mathematically, the standard form of the equation of a straight line is given by;
y = mx + c
Where:
- x and y are the points.
- m is the slope.
- c is the intercept.
At point (4, 300), we have:
y = mx + c
300 = 50(4) + c
300 = 200 + c
c = 300 - 200
c = 100.
Therefore, the equation of this straight line is y = 50x + 100.
