Question

Write the equations for 74,2 and 49

Answer 1

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:

$x+10y=94$
