Need more context. It says how much does Grayson need to score? Does this mean there’s a certain score Grayson needs to reach to win? Or is it just a random scenario for a pattern question?
Answer: 
<u>Step-by-step explanation:</u>
If you solve for y, then it will be in y = mx + b format where m is the slope.
3x + 5y = 29
<u>-3x </u> <u> -3x </u>
5y = -3x + 29
m =

Answer: A. True</h3>
=====================================================
Explanation:
Let x be the number of years since 1995. So x = 0 represents 0 years from 1995, x = 1 is 1 year after 1995, and so on.
The first row of the table is (x,y) = (0, 625) with y being the number of salmon.
The second row is (1, 400).
Let's find the slope of the line through these two points.
m = (y2-y1)/(x2-x1)
m = (400 - 625)/(1 - 0)
m = (-225)/1
m = -225
This tells us the salmon population dropped by 225 in the course of a year from 1995 to 1996.
-------------------------------
The third row shows (2, 225). Let's find the slope of the line through the two points (1, 400) and (2, 225)
m = (y2-y1)/(x2-x1)
m = (225 - 400)/(2-1)
m = (-175)/(1)
m = -175
The slope is different from the previous result. Because of this discrepancy, this means we do not have a linear model. The slope should be the same for any two points you pick from this table if you wanted a linear model.
Put another way, there is less steep a drop of the population, and the decay curve is slowly flattening out.

</h2>
Step-by-step explanation:
x - y² = -1 ⇒ - y² = - x - 1 ⇒ y² = x + 1 {x≥-1}
4x² + 9y² = 72
4x² + 9(x + 1)² = 72
4x² + 9(x² + 2x + 1) = 72
4x² + 9x² + 18x + 9 - 72 = 0
13x² + 18x - 63 = 0 ⇒ a = 13, b = 18, c = -63
