## kris2685 Group Title write an equation of the line containing the specified point and perpendicular to the indicated line (0,6),2x -5=y one year ago one year ago

Ok so all you need is a point and a slope. You already have your point (0,6) and now all you need is the slope which you can get from this line: 2x -5=y

2. RyanL. Group Title

Can you tell me the slope of the line 2x -5=y

3. kris2685 Group Title

-3

4. RyanL. Group Title

y=mx+b

5. RyanL. Group Title

where m is the slope. Can you give it one more shot and tell me the slope?

6. kris2685 Group Title

2

7. RyanL. Group Title

great but since the line we are looking for is perpendicular to this the slope actually has to be a negative reciprocal. That's fancy math talk of saying - 1/2

8. RyanL. Group Title

now we use the point slope form. $y-y_1=m(x-x_1)$ where $(x_1,y_1)=(0,6)$$m=-\frac{1}{2}$

9. RyanL. Group Title

plug that in and solve for y if you have to.

10. RyanL. Group Title

Get it?

11. kris2685 Group Title

y= -1/2 x-6

12. RyanL. Group Title

y= -1/2 x+6 actually because you add 6 to both sides. But close enough good job!

thank you
