Answer:
Step-by-step explanation:
Y=mx+b
Slope (m) is rise over run.
1. rise= 4 run=5 therefore, slope=4/5
y=4/5x+b
b= y intercept
b= 4
Y=4/5x+4
2. rise= 1 run= 2 slope = -1/2
b= -1
Y= -1/2x - 1
Answer:
Step-by-step explanation:
If the series has a fixed gap between entities (terms).
Add the first and the last values and multiplied by the half of number of terms
For example
2,4,6,8,10 = 5/2 (2 + 10) =30
2+4+6+8+10 =30

Answer:
f(2) = 28
Step-by-step explanation:
Answer: ∠R = 137°
<u>Step-by-step explanation:</u>
The opposite angles of a quadrilateral are supplementary (equal to 180°).
Since ∠P and ∠R are opposite angles, their sum is 180°
∠P + ∠R = 180°
y + 3y + 8 = 180
4y + 8 = 180
4y = 172
y = 43
∠R = 3y + 8
= 3(43) + 8
= 129 + 8
= 137
