Someone please help

Answer:

1. y = -2x + 5

2. y = 3/5x + 5

3. y = -4/5x - 4

4. y = - 1

5. yes

6. yes

7. yes

8. no

Step-by-step explanation:

1. (4,-3) parallel to y= -2x

-3 = -2(4)+b

b=5

2. (-5,2) parallel to y = 3/5x

2= 3/5(-5)+b

b=5

3. (-5,0) -4/5x

0 = -4/5(-5)+b

b = -4

4. (-4,-1)

y= -1

5. yes

6. yes

7. yes

8. no

Same slope = parallel ex. y = -5x +7, y = -5x +12
opposite reciprocal = perpendicular ex. y = -5x +7, y = 1/5x + 12
to find "b" with slope and point

(x,y) y = mx + b

plug in the y value and x value in the eqaution and m=slope, solve for b
