GRAPH THE LINE
GRAPH THE LINE:
1) slope = 1 /5 ; Point (0, 3)
(0,3) (5,4) (10,5)
1) A car rental agency charges $30 plus $0.25 per mile for each mile driven
Therefore, 30 is the initial value which is our y-intercept. slope= 0.25
GRAPH THE LINE
2) slope = –2 ; Point (–1, 2)
(-1,2) (0,0) (1,-2)
find slope and y-intercept
y = –40 x + 20
slope = –40
y-intercept = 20
GRAPH THE LINE
3) slope = 5 ; Point (–2, –2)
(-2,-2) (-1,3) (0,8)
find slope and y-intercept
4) y = 2x – 10
slope = 2
y-intercept = –10
GRAPH THE LINE
4) slope = –2/3; Point (3, –1)
(3,-1) (6,-3) (9,-5)
2) A 2000 gallon pool is being emptied at a rate of 200 gallons per hour.
y-intercept = 2000
slope = 200
PG. 55 1) Determine the slope and the y-intercept for each representation.
slope: 2
y-intercept: 4
Find the slope and the y-intercept for each representation.
1) A wild animal park opens with 100 antelope and the population grows 5 antelope per year.
2) y = (–1/2)x + 3
1) slope: 5 y-intercept: 100
2) slope: –1/2 y-intercept: 3
