Answer:
<u>1st graph</u>:
Slope-intercept is y = -7/2x + 3
Point Slope is y + 4 = -7/2(x - 2)
Standard is 7x + 2y = 6
<u>2nd graph</u>:
Slope-intercept is y = 1/2x - 4
Point Slope is y + 2 = 1/2(x - 4)
Standard is x - 2y = 8
<u>3rd graph</u>:
Slope-intercept is y = 3x - 3
Point Slope is y - 3 = 3(x - 2)
Standard is 3x - y = 3
<u>4th graph</u>:
Slope-intercept is y = -2/7x - 4
Point Slope is y + 2 = -2/7(x + 7)
Standard is 2x + 7y = - 28

Sorry this took a while, I was doing other stuff for school. I also had to relearn point slope for this, so it took me some time to figure it out. Hope this helps though :)
Answer:
Step-by-step explanation:
Given
Total = 900
Singing = 600
Dancing = 500
None = 125
Required
Determine the number of students that participate in both
Representing; Singing with S, Dancing with D, Both singing and dancing with B and None with N;
In Set Notation;
Substitute 900 for Total, 600 for S, 500 for D and 125 for N
Open Brackets
Collect Like Terms
Collect Like Terms
Multiply both sides by -1
Reorder
<em>Hence, the number of students that do not participate in both is 325</em>
