Question

(picture in comments) I will fan/medal for help :)

Calculate the slope of line BD.

Answer 1

Answer choices:

a. 1
b. -1
c. \[\frac{ 1 }{ 4 }\]
d. \[\frac{ 1 }{ 7 }\]

Answer 2

if i remember correctly slope formula is y1-y2/x1-x2 which in the end i think might equal to 1 cause it will end up being 3/3

Answer 3

Yeah I know the formula but it just confuses me :/ Could you help me with a few more?

Answer 4

sure

Answer 5

so you would use the formula and fill in your numbers. 11-9 over 4-(-6) (which would be 4+6) which would equal 2/10 so 1/5

Answer 6

again for the next one it would 7-7 over 3-(-3) which would equal 0/6 so undefined

Answer 7

Calculate the equation of the line between the points (-6,-1) and (2,-1).

a. y=-1
b. x=-1
y=-8x-1
d. y=-x-8

Answer 8

If MN is the diameter of a circle with M(-3,-4) and N(-7,-14), find the center of the circle.

a. (-2,-5)
b. (-4,-10)
c. (-5,-9)
d. -10,-18)

Answer 9

equation of the slope is y=mx+b so for that question they give you your slope which is 3/7 and I'm pretty sure your b would be -2 so C.

Answer 10

Where P is (-2,6), R is (-10,4) and segment RT is a diameter of Circle P, find the coordinates of T.

a. (-4,-12)
b. (6,8)
c. (8,2)
d. (8,6)

Answer 11

Last one!
What is the y-intercept of 12+4y=10?

a. 2.5
b. -3
c. 4
d. -12
