Answer:
see the explanation
Explanation:
we know that
The linear equation in slope intercept form is equal to

where
m is the slope
b is the y-intercept
Part 1) we have

This is the equation of a line in slope intercept form
therefore
The slope is m=-4
The t-intercept is b=-6
see the attached figure to better understand the problem
Part 2) we have

This is the equation of a line in slope intercept form
therefore
The slope is m=-1/2
The t-intercept is b=-1/3
