Point slope form is:
y -
= m(x -
)
With
and
being the coordinate points, and m being the slope.
So the coordinate points are (4, -5), and the slope is -6 in this case.
So just substitute everything in, to get:
y - ( -5) = -6(x - 4)
Or
y + 5 = -6 (x - 4)
858.666666666666666666666666666666666666666666666666666666666
It would be: y-y1 = m(x-x1)
y-8 = m(x+16)
y-8 = mx+16m
y = mx+16m+8
you have to calculate m, which can be possible if two coordinates are given otherwise it's the final possible answer...
Answer:
Define F as fathers age and S as sons age right now.
Then now they are
(1) 3S = F
and six years ago they were
(2) 5*(S-6) = F-6
calculate 5*(S-6)
5S - 30 = F-6
Subtract left and right side by -F
Add 30 to left and right side
5S - F = 24
Put (2) 3S = F into the equation above
5S - 3S = 24
2S = 24
S = 12
insert result in (2) 3S = F
3*12 = F
36 = F
Step-by-step explanation:
So the son is 12 years, and the father is 36 years.
Domain is the x values and Range is the y values
