Answer:
y=1.5x+2
Step-by-step explanation:
Step 1, find slope
(20-8)/(12-4)
12/8 = 1.5
slope = 1.5
Step 2, find the y-intercept
y = 1.5x+b
use point (4,8)
8 = 1.5(4)+b
8 = 6+b
-6 -6
2 = b
Step 3, put it all in slope-intercept form (y = mx+b)
y = 1.5x+2
Answer: y = 1.5x+2

Answer:
x = 20
B = 92
C = 40
Step-by-step explanation:
The three angles of a triangle add to 180 degrees
A+B+C = 180
48+6x-28+2x = 180
Combine like terms
20+8x =180
Subtract 20 from each side
20+8x-20 = 180-20
8x = 160
Divide each side by 8
8x/8 = 160/8
x = 20
Then we need to find angle B
B = 6x-28 = 6(20)-28 = 120-28 =92
Then we need to find angle C
C = 2x = 2(20) = 40
Do you mean this way?
y - 3 = 1/2x + 1 => y = 1/2x + 4
