(2,5)(-1,5)....notice that ur y's are the same number...they are both 5.
This means that u have a horizontal line which has a slope of 0. If the y's are the exact same number, then u have a horizontal line.
if the x's would have been the same number, then u would have had a vertical line with an undefined slope
Answer:
7 and 8, 2 and 28, 1 and 56, 4 and 14
Step-by-step explanation:
For this, the number we are looking for is x.
use this formula... 17 - 3 = 2x
therefore, 14 is your doubled number.
14 divided by two is 7.
your mystery number is 7
If you have a graphing calculator just put in the equation in 'y=' (not the i equation), and then go to 2nd trace and see where the y=0, those numbers under the x column are the zeros. For the first one, the zeros are: -1, .5, and 2.8. For the second question the zeros are: -3 and about 1.9. The zeros with a decimal are estimations.
