Question

check my sisters answers please
what is the slope of the line that passes through the pair of points (-7/2,-3) and (-5, 5/2)?
6/22
-6/22
22/6
-22/6

Answer 1

she says she thinks it is 22/6 is she right?

Answer 2

y^2-y^1
-------
x^2-x^1
All you have to do is plug the points into the equation

Answer 3

@emilyhaddad

Answer 4

it's -22/6

Answer 5

ok ill explain the signs to her she forgot that they switch sometimes during the whole transition of it all

Answer 6

also she wants to know if this one is right
write an equation in point slope form for the line through the given point with the given slope
(5, -6); m = -0.38
y + 6 = -0.38(x + 5)
y - 6 = -0.38x - 5
y - 6 = -0.38(x + 5)
y + 6 = -0.38(x - 5) she thinks it is the last one is she right?

Answer 7

Yes sir!

Answer 8

hah thx she really appreciates it

Answer 9

no problem!

Answer 10

hey she has another question willing to help?

Answer 11

for the data in the table does y vary directly with x if it does write an equation for the direct variation
x y
32 24
16 8
8 6
yes y = 0.5x
yes y = 2x
yes y = 1.5x
no y does not vary directly with x
she says she thinks it is yes y = 2x
