The figure at left was made by first drawing line segment AB, and then drawing JK, which is a segment of the perpendicular bisector of AB.
Which of the following statements must be true?
A
Triangles AJB and AKB are isosceles.
B
Triangle AKB is isosceles, but triangle AJB is not.
С
Triangles AJB and AKB are congruent.
D
Triangles AJK and AJB are congruent.

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.
