Question

Can anybody help me?

Answer 1

yaaaa

Answer 2

Depends on what you need help with

Answer 3

The equation of line CD is y = 3x − 3. Write an equation of a line perpendicular to line CD in slope-intercept form that contains point (3, 1).

Answer 4

a)y = 3x + 0

b)y = 3x − 8

c)y = negative 1 over 3x + 2

d)y = negative 1 over 3x + 0

Answer 5

Okay so what do we know about the slopes of perpendicular lines?

That they are negative reciprocals of each other yes?

Answer 6

yes

Answer 7

So to find a negative reciprocal slope, we do -1/slope

The slope they gave us is 3. So what would the slope of the line perpendicular to this one be?

Answer 8

-1/3

Answer 9

Great so that means we can eliminate 2 answer choices.

Answer 10

Now, does this ring a bell?

Answer 11

yes isn't that the slope intercept formula

Answer 12

So we plugged it in, we have to arrange it into slope intercept form by adding 2
