Answer:

Step-by-step explanation:
Question 1
The point-slope formula for a straight line is
y – y₁ = m(x – x₁)
x₁ = 3; y₁ = -5; m = -4
Substitute the values

The diagram shows the graph of equation 1 (red) with slope -4 passing through (3,-5).
Question 2
x₁ = -1; y₁ = 8; m = 1
Substitute the values

The diagram shows the graph of equation 2 (green) with slope 1 passing through (-1,8).
Reduced by half = 200cm/50 seconds.
20000/50 = 400.
200 x 400 = 80,000cm
Well, that would be 4 tables to fit 20 people but would not be enough for 2 more people so I would say 5 tables total.
-Hope this helps.
1st year 500* 0.03 = 15+500=515
2nd year 515*0.03= 15.45 + 515 = 530.45
3rd year 530.45*0.03= 15.9135 + 530.45 = 546.3635
4th year 546.3635 * 0.03 = 16.390905 + 546.3635 = 562.754405
562.754405
(4x+2)²-3
16x²+4-3
16x²+1
Hope this helps :)
