Answer: Choice A
The number line graph is visually showing every number that is 19 or smaller; hence
Note the use of a closed or filled in circle at the endpoint (in contrast to an open circle). This indicates we are including the endpoint 19 as part of the solution set, and that's why we go for "or equal to" as part of the inequality sign.
Answer:
y=-3x+5
Step-by-step explanation: y=mx+b
to find slope (m) use the equation
so
= -3
to find b
use y=mx+b
-1=-3(2)+b
-1=-6+b
5=b
Hope this helps :)
