1)
table
x f(x)
1 -7
2 -10
3 -13
4 -16

slope: rise / run = [-10-(-3)]/1 = -3
y-intercept: x=0=> y = -4 =b

equation: y = -3x - 4 ..... this is the rule

2) table

x f(x)
1 3
2 2
3 1
4 0

slope: rise / run = [2 -1] / [2 - 3] = -1
y-intercep: x = 0 => y = 4 = b

equation: y = -x + 4 .... this is the rule
