What the answer please

Step-by-step explanation:

To find y=mx+b we need to identify two points. I picked (20,45) and (50,65)

From these two points we can find the slope, m.

m=(y2-y1)/(x2-x1)

m=(65-45)/(50-20)

m=20/30=2/3 so now our line is

y=2x/3+b, we can solve for b using either point, I’ll use (20,45)

45=2(20)/3+b

45=40/3+b

b=45-40/3

b=(135-40)/3

b=95/3 so the line is

y=(2x+95)/3

answer: 0+0=0

step-by-step explanation:

that is the only answer that can make 0

so, converting firstly the mixed fractions to improper fractions and then "adding".
