Question

write the equation of the line that has a y-value that increaes by 4 for every 4 for every x that increases by 1. it also crosses the y-axis at -2.


a. y=4x-2
b. y=1/4x-2
c. y=2x+1/4
d. y=2x-4

Answer 1

so the gradient would be rise/run which is equal to 4/1. the gradient is 4

Answer 2

the graph cuts the point (-2,0)

Answer 3

okay so its A? :D

Answer 4

yup

Answer 5

sorry it should be (0,-2)

Answer 6

instead of (-2,0)

Answer 7

so its D
:)

Answer 8

nope it still A

Answer 9

the y intercept is -2

Answer 10

y=mx+c
c is the y intercept

Answer 11

aww okay thanks, you're awesome! :D

Answer 12

m is the gradient which is 4/1

Answer 13

no prob :)

Answer 14

:)
you're very smart! lol im not.
