Write an<br> equation of the line that passes through each pair of points.<br> (-3,9), (-3,-5)
fgiga [73]

Answer:

since slope(m) = y2 -y1/x2- x1

-5 - 9/ -3 - (-3)= -14/0

m = -14/0 (undefined)

using the formula

y-y1 = m(x -x1)

y - 9 = -14/0(x - (-3)

y-9 = -14/0(x + 3)

0 = -14( x+3). (cross multiplication)

0 = -14x - 42

14x = -42

x = -3( equation of the line)

How to find rate of change on a table
LekaFEV [45]

Answer:

   __X__l__Y_

        1     l    3

        5    l    6

        9     l    9

        13   l    12

        17   l    15

        21   l    18

On the right side, the numbers get larger by adding three each time. On the left side, the numbers get larger by adding 4 each time. It would be the same for any other pair of numbers when you add 4 to the left, and 3 to the right. For instance, the next pair would be (25 , 21). 25 would be the X value, and 21 would be the Y value.
