No idea what the second one is but this is the first one Y=-2/3 x+66.66666666

Step-by-step explanation:

For no.4

m= -2/3

x=-60

y=10

now

y=mx+b

or,

10=-2x/3+b

or, 30=-2(-60)+3b

or, 30 = 120+3b

or,

3b = -90

so, b = -30

now

y=mx+b

or, y = -2x/3-30

for no.4 the equation would be

y = -2x/3 - 30
