The answer to your question is a)  y = 1.5x - 6    

                                                    b)   y = -4x + 6.1

                                                    c) Point (2.2, -2.7)

Step-by-step explanation:

First line                                                Second line

P (0, -6)           Q (1, -4.5)                        R (0, 6.1)       S (1, 2.1)

m = (-4.5 + 6) / (1 - 0)                              m = (2.1 - 6.1) / (1 - 0)

m = 1.5 / 1                                                m = -4/1

m = 1.5                                                    m = -4

Line                                                         Line

  y - y1 = m(x - x1)                                   y - 6.1 = -4(x - 0)

  y + 6 = 1.5(x)                                        y - 6.1 = -4x

  y = 1.5x - 6                                           y = -4x + 6.1

Solve the system by equality

                             1.5x - 6 = -4x + 6.1

                              1.5x + 4x = 6.1 + 6

                                    5.5x = 12.1

                                         x = 12.1 / 5.5

                                         x = 2.2

Find y

                             y = 1.5(2.2) - 6

                             y = 3.3 - 6

                             y = -2.7

Point (2.2, -2.7)

1.677

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.
