Linear Equations

100

find the slope of line 

y= 2x+ 8

slope= 2

200

find the slope and the y intercept

Y=2/3x - 16

slope= 2/3

y intercept= -16

300

find the slope and y intercept

2y=-12x+4

slope=-6

y intercept=2

400

solve for y

2x-3y=6

y=2/3x-2

500

find the slope and y intercept

y+1=4/3x

slope= 4/3

y inter= -1

Linear Functions

100

is this a linear function 

yes or no

y=2x-3

yes

200

is this a linear function 

yes or no

points (-3, 9) (-1,1) (1, 1) 

no

300

is this a linear or nonlinear function?

2 + x - y = 12

nonlinear 

400

would this line be curved or straight when graphed? How do you know? 

(3, 4) (6, 5) (9, 8)

curved, there is not a constant rate of change on the y axis. 

500

explain if this line would be linear or nonlinear. 

Luke is biking. He is going at a constant speed for a while before taking a few minutes break. When he starts biking again, he gradually gets slower until the end of his bike ride. Would this be linear or nonlinear? 

nonlinear
