Question

please help with equations

Answer 1

So perpendicular lines must intersect. This means their slops cannot be the same.

Answer 2

perpendicular lines have negative reciprocal slopes

Answer 3

Slopes*

Answer 4

so if one of the two lines has 3/5 slope, a line that is perpendicular to it, will have a slope of -(5/3)

Answer 5

A also displays -3/7 as the slope.

Answer 6

No it's A or C.

Answer 7

that is something you need to answer.
in a point-slope form y - y1 = m(x - x1)
m is the slope and (x1, y1) is the coordinate of the given point

Answer 8

even if you have to guess, always make sure that you follow certain logic when doing so.

Answer 9

No, >.>

Answer 10

.________________. You only need the slope of the given eqaution, they want the perp so its -3/7

(-4,9)

y-9=-3/7(x-(-4))

y -9=-3/7(x+4)

Answer 11
