I'll do the first two to get you started.


# 1



5y-2x%2B8=0 Start with the given equation.


5y%2B8=0%2B2x Add 2x to both sides.


5y=0%2B2x-8 Subtract 8 from both sides.


5y=2x-8 Combine like terms on the right side.


y=%282x-8%29%2F%285%29 Divide both sides by 5 to isolate y.


y=%282%2F5%29x-%288%2F5%29 Break up the fraction.


Now the equation is in slope intercept form y=mx%2Bb where the slope is m=2%2F5 and the y-intercept is b=8%2F5





# 2

Since the equation x=-9 is not in slope intercept form, this means that the slope is undefined and there is no y-intercept (the line is parallel to the y-axis).
