Question

Write a rule for the linear function whose graph has slope m and contains the given point.
m = 3; (-2, -2)
a.
y = 3x + 4
c.
y = 3x + 2
b.
y = 3x - 4
d.
y = 3x - 2

Answer 1

y=mx+b

Answer 2

y=3x+b...
b=y-3x...
let x=-2
let y=-2
and (x=y)
b=(-2)-3(-2)
b=(-2+6)
b=6-2
b=4.
hence,
y=mx+b
becomes...
m=-3
b=4
becomes...
Ans. y=-3x+4.....!
y=3x-4!
which also equals
y=3x-4....
hence the answer is...
