Answer:
Please check the explanation.
Explanation:
The slope-intercept form of the line equation
y = mx+b
where
Part a)
Given the equation

Writing the equation in the slope-intercept form of the line equation

adding 3y to both sides


flip the equation

divide both sides by 3

Thus, the equation in the slope-intercept form is:

Part b)
As the equation in the slope-intercept form is

comparing with the slope-intercept form
Part c)
Given the equation

The graph is attached below.
From the given graph, is clear that:
at x = 0, the value of y = -3
Thus, the y-intercept of the equation is b = -3
Please check the attached graph.
