Answer: y = -1/4x - 4
Step-by-step explanation:
y = (-1/4)x + 2 (This is the first linear function.)
(4,3) has slope of (-1/4)x or (1/-4)x
4(y2) - 4(y1= the new y -1(x2) -3(x1) = new x which leads to (0,-4) so y-intercept = -4
so all in all, y = (-1/4)x -4 is the answer
Hopefully, you're able to understand this. It's difficult to explain through typed words rather than visually and through a written example.

Answer:
(a)3
(b)4
(c)6
(d)5
Step-by-step explanation:
(a)Josie rolls a six-sided die 18 times.
P(she rolls a two)=1/6
Therefore, the estimated number of times she rolls a two in 18 trials
=1/6 X 18
=3
(b)Slips of paper are numbered 1 through 10.
P(the number 10 appear)=1/10
If one slip is drawn and replaced 40 times, expected number of 10
=1/10 X 40
=4
(c)A spinner consists of 10 equal- sized spaces: 2 red, 3 black, and 5 white.
P(red)=2/10
If the spinner is spun 30 times, expected number of red space
=2/10 X 30
=6
(d)A card is picked from a standard deck
P(drawing an ace)=4/52
If the card is picked 65 times and replaced each time.
Expected Number of Aces =4/52 X 65 =5
