Step-by-step explanation:
Question 5)
The given graph is a straight line.
We know that the graph of a linear function is a straight line that can be written in the form
where m is the slope and b is the y-intercept
The slope of the line can be determined by taking two points
(3, -3)
(-2, 3)
Finding the slope
From the graph, the y-intercept can be obtained by setting x=0 and check the corresponding y-value of y.
or substituting m = -6/5 and (3, -3) in the slope-intercept form to determine y-intercept 'b'.
now substituting m = -6/5 and b = 3/5 in the slope-intercept form to determine the equation of the linear function
y=mx+b
y = -6/5x + 3/5
Therefore, the relation is a linear function with the equation: y = -6/5x + 3/5
