Write the equations for 74,2 and 49

Mathematics
1 answer:
serious [3.7K]3 years ago
5 0

Answer:

x+10y=94

Step-by-step explanation:

Assuming we want to find the equation (74,2)  and (4,9)

This is an equation of a straight.

Let this equation be y=mx+b.

m=\frac{9-2}{4-74} =-\frac{1}{10}

We substitute the slope  and (4,9) to get:

y-9=-\frac{1}{10}(x-4)

We  rewrite in standard form to get:

x+10y=94
