Help with first 2 please

just put the values of x,you find value of y

for example:x=-2

y=x-1

y=-2-1=-3

plug in the values of x into each equation

1.  y = 2x + 5         original equation

y = 2 (-2) + 5        plug in the x value

y = -4 + 5             simplify

y = 1 (-2 would make 1)

Therefore, -1 would make 3, 0 would make 5, 1 would make 7, & 2 would make 9.

2. y = 3/8x - 5     original equation

y = 3/8 (-8) - 5    plug in the x value

y = -3 - 5             simplify

y = -8 (-8 would make -8)  

Thereofre, 0 would make -5, 8 would make -2, 16 would make 1, 24 would make 4.

(w – 2.5)(w + 2.5)

(–4v – 9)(–4v + 9)
