DB bisects ABC
Prove: mCBD=45 degrees

A:
division,
definition of bisects,
definition of right angle,
given
B:
measure of angle ABC=90
Measure of angle ABC=180
Measure of angle ABD=90
Measure of angle CBD=180
C:
Addition
Angle addition postulate
Definition of right angle
Substitution property
D:
Angle ABC=90
Angle ABD=90
2 times the measure of angle ABC=90
2 times the measure of angle CBD=90

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.
