 y=4,728,779,608,739,020,800

Step-by-step explanation: based on the values you have for m & b it would be...

y=4,200 x

y=4,200 x 1,125,899,906,842,624

y=4,728,779,608,739,020,800

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
