Question

Choose the equation of the line passing through the point (-1, 7) and perpendicular to y = -negative one fourthx - 5.

y = -4x - 11

y = -4x - 3

y = 4x + 11

y = 4x + 3

Answer 1

y = -negative one fourthx - 5
slope is -1/4=m
when perpendicular m' *m=-1
so m'=+4

Answer 2

now
write the line with slope +4 and passing through the point (-1, 7)

Answer 3

according to my calculations, the answer is y=4x + 8
i used the slope-point formula

Answer 4

so the slop is 4

Answer 5

y-y0=m'(x-x0)

y-7=4(x-(-1))
y-7=4x+4
so y=4x+11

Answer 6

thanks
