▹ Answer
<em>1. x = -7</em>
2. y = 7
▹ Step-by-Step Explanation
x - y = -7
x - 0 =7
x = -7
x - y = -7
0 - y = -7
y = 7

The answer to this is y = 3x - 2.
In the slope-intercept form y=mx+b, b is your y-intercept and in this problem, it will be -2. M is the slope which is 3.
Y=6x+9. y=6x+2. Therefore y=6x+9=6x+2. 6x+9=6x+2. 6x-6x=2-9. 0=-7. This is not true. So this is- No solution
Part A: Factor 3x2y2 − xy2 − 2y2. Show your work. (4 points)
3x^2y^2 − xy^2 − 2y^2
y^2 ( 3x^2 - x -2 )
y^2 (3x+2)( x - 1)
Part B: Factor x^2 + 6x + 9. Show your work. (3 points)
x^2 + 6x + 9
= x^2 + 2*3x + 3^2
= (x+3)(x+3)
= (x+3)^2
Part C: Factor x2 − 25. Show your work. (3 points)
x^2 - 5^2
