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

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

OpenStudy (anonymous):

the graph cuts the point (-2,0)

OpenStudy (anonymous):

okay so its A? :D

OpenStudy (anonymous):

yup

OpenStudy (anonymous):

sorry it should be (0,-2)

OpenStudy (anonymous):

instead of (-2,0)

OpenStudy (anonymous):

so its D :)

OpenStudy (anonymous):

nope it still A

OpenStudy (anonymous):

the y intercept is -2

OpenStudy (anonymous):

y=mx+c c is the y intercept

OpenStudy (anonymous):

aww okay thanks, you're awesome! :D

OpenStudy (anonymous):

m is the gradient which is 4/1

OpenStudy (anonymous):

no prob :)

OpenStudy (anonymous):

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

OpenStudy (anonymous):

nah.. i just started learning it 2 weeks ago. you can research online for help too
