<u>Given:</u>
Given that the graph of a linear function.
We need to determine the equation of the graph in slope intercept form.
<u>Slope</u>:
Consider any two coordinates from the equation of the line to determine the slope.
Let the two coordinates are (-4,3) and (4,-1)
The slope can be determined using the formula,
Substituting the coordinates in the above formula, we get;
Thus, the slope of the equation is
<u>Value of y - intercept:</u>
The value of y - intercept is the value of y when x = 0.
Hence, from the graph, it is obvious that the value of y when x = 0 is 1.
Hence, the value of y - intercept is 1.
Thus, y - intercept is
<u>Equation of the line:</u>
The equation of the line can be determined using the formula,
Substituting the slope and the y - intercept
Thus, we get;
Thus, the equation of the line is
