Answer 2

Find three solutions of the equation y=7x-5.
a.(3,-26),(1,-12),(3,16)
b.-3,-26),(-12,-1), (16,3)
c.(-3,-26), 3,16), (1,-12)
(-3,-26), -1,12), (2,16)

Answer 3

plug and play ....

Answer 4

which pair of points has a negative slope?
(-3,17), (2,-8)
(-3,13), (3,17)
(4,26),(-2,-10)
(4,14), (-2,-4)

Answer 5

also need help with this

Answer 6

use the slope formula for the slope one ...

Answer 7

a shortcut would be to subtract the second point from the first and if they have same signs .. they are positive slope.

Answer 8

ok

Answer 9

so if i put them into a coordinate plane just find the negative slope

Answer 10

Answer 11

thats a good thought, if youve got paper and pencil, plot them relative and draw the line

Answer 12

ok, but i still need help this the firsst one

Answer 13

(4,26)

(-2,-10)

moves up when we go left to right ... so its positive

thats a good method if the mathing is a bother :)

Answer 14

the first one, its just plugging in values to see if they are true.

i cant multiply and add for you ... what about it is not setting with you?

Answer 15

idk

Answer 16

y=7x-5

is (3,-26) a solution?

how do we chk?

Answer 17

im unsure

Answer 18

the only thing i can imagine then is that you do not know how to read a point.

(3,-26) means: (x=3, y=-26)

y=7x-5

plug them in and see if its true ...

-26=7(3)-5 is this true?

Answer 19

thanks for the help. i got to go.

Answer 20

good luck
