A. use the points (5, 1,273) and (10, 2,546) to write
an equation for the line.

y = 254.6x

Step-by-step explanation:

Start by finding the slope of this line:

y1-y2/x1-x2 = m   2546-1273/10-5 = 1273/5 = 254.6

So, your slope is 254.6

Now, we have to find the y-intercept (if any)

y=mx+b First, plug in a point:

1273=254.6(5) + b

1273=1273 + b

-1273    -1273

b=0

This means your line is a direct variation

The equation is y=254.6x

answer is 144
