consider the line whose equation is 4x-8y=8

A.) write the equation in slope-intercept form

B.) write a slope of a line perpendicular to this line

C.) write the equation of the line, in point-slope form, that is perpendicular to the line that passes through the point (1, 2)

slope-intercept form -> y = mx + b
so you want to isolate y from   4x-8y=8

anonymous · Answer

A.) I have y=1/2x-1 B.) I have y=2/1-1

jigglypuff314 · Answer

the first is correct
mmm for the second if you meant  (2/1)(-1)  then yes :)

anonymous · Answer

is there still the y=

jigglypuff314 · Answer

slope is represented by the letter  m 
so   m = -2
