Answer:
Please check the explanation.
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
- m is the slope
- b is the y-intercept
Part a)
Given the equation
[tex]9x-3y-9=0[/tex]
Writing the equation in the slope-intercept form of the line equation
[tex]9x-3y-9=0[/tex]
adding 3y to both sides
[tex]9x-3y-9+3y=0+3y[/tex]
[tex]9x-9 = 3y[/tex]
flip the equation
[tex]3y = 9x-9[/tex]
divide both sides by 3
[tex]y=3x-3[/tex]
Thus, the equation in the slope-intercept form is:
[tex]y=3x-3[/tex]
Part b)
As the equation in the slope-intercept form is
[tex]y=3x-3[/tex]
comparing with the slope-intercept form
- The slope m = 3
- The y-intercept b = -3
Part c)
Given the equation
[tex]y=3x-3[/tex]
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.
