First find the slope using the slope formula M= (y2-y1) divided by (x2-x1) and then take the slope and and the 1st set of points (x1, y1) and plug it into the slope intercept formula which is y-y1=m(x-x1), then you need to add or subtract variables to correlate with the standard form formula which is ax + by = c.
Hope that helps!
Answer: He makes $111.80 in 2 days.
Step-by-step explanation:
Since we have given that
Amount he makes in 3 days = $167.70
Number of days = 3
We need to find the amount he makes in 2 days.
We will use "Unitary method" to find the amount s in 2 days.
In 3 days , amount = $167.70
In 1 day, amount is given by

In 2 days, amount is given by

Hence, he makes $111.80 in 2 days.
