Answer:
The slope of the line passing through the given points (-2,-7) and (9,-7) is m=0
Step-by-step explanation:
Given that the line passing through the points (-2,-7) and (9,-7)
To find the slope of the line passing through the points :

Let
and
be the given points (-2,-7) and (9,-7) respectively
Substitute the points in the formula 



Therefore m=0
Therefore Slope m is 0
Therefore the slope of the line passing through the given points (-2,-7) and (9,-7) is m=0
3 factors of 4, 6, 9, 14 and 49 are 2, 3 and 7
The angle of NPR is 130°
First, set up an equation to find x.

Then, solve the equation for x.

Then, substitute 25 in for x in 2x
50
Finally, subtract 50 from 180 to find the angle of NPR
130°
Answer:
54 teachers
Step-by-step explanation:
Students ratio :17+18=35 then 630/35= 18 18x3t=54
256 being rounded would become 260 and 321 would become 320 so adding up the estimates the would be 580 (real answer is 577)
