4. what does decreasing the constant c by
5 units in an equation of the form
y = x2 – 3x + c do to its graph?
a. it translates the graph 5 units to
the right.
b. it translates the graph 5 units to
the left.
it translates the graph 5 units up.
d. it translates the graph 5 units down.
c.
it translates the graph 5 units up

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.

the first option i believe
