Answer is B
Each number under the leaf side is the other half of the stem.
Therefore,
1 | 7 =1.7
1 | 3 =1.3
3 | 7 =3.7
So on and so forth.
Answer:
Step-by-step explanation:
Slope of line through (0,-1) and (1,2) = (-1 - 2)/(0 - 1) = 3
Point-slope equation for line of slope 3 that passes through (0,-1):
y+1 = 3(x-0)
When x = 2:
y+1 = 3(2-0)
y = 3·2 - 1 = 5
When x = 3:
y+1 = 3(3-0)
y = 3·3-1 = 8
Okay so slope intercept form is y=mx+b
Where b is the y intercept, m is the slope and x is the changing variable. So in this case let x represent the number of hours and m equal the cost per hour $2. That leaves $5 as the y intercept. So your equation is y=2x+5
