What is the equation of the line that passes through the points (−1, 3) and (1, 11)? 4x − y = 1 4x + y = 1 x − 4y = −13 4x − y = −7

OpenStudy (amistre64):

we should subtract our points

OpenStudy (anonymous):

just plug the points in and see which one makes sense for both points.

OpenStudy (amistre64):

(1, 11) -(−1, 3) -------- 2 , 8 does what i did there make sense

OpenStudy (anonymous):

it should be the last one. 4x-y = -7

OpenStudy (amistre64):

yes, it should be :)
