Answer:
As the line equation represents a straight line, so the relationship between x and y is a straight line.
Therefore, option E is true.
Step-by-step explanation:
Taking two points from the given line
- (3, 0)
- (-3, -2)
Finding the slope between two points
From the graph, the y-intercept can be calculated by setting the x=0 and then check the corresponding value of y.
at x = 0, y=-1
Thus, the y-intercept = -1
We know that the slope-intercept form is
where m is the slope, and b is the y-intercept
substituting the values of m=1/3 and the y-intercept b = -1
As the line equation represents a straight line, so the relationship between x and y is a straight line.
Therefore, option E is true.
