What is the constant in this expression? m-4n+3.5+4/5p

3.5

Step-by-step explanation:

We are given that an expression

We have to find the constant in the given expression

Constant:That number which is numerical number and do not change remain same.

Variable : That number which is represented by letter x, y  etc and varying and do not remain  same.

In the given expression 3.5 is constant because 3.5  is fixed and do not change.

Hence, 3.5 is  constant.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
