The answer is
<h2>Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of a line given a point and slope we use the formula
y - y1 = m(x - x1)
where
m is the slope
( x1 , y1) is the point
From the question the point is ( 1 , 2) and the slope is 1/2
Substitute the values into the above formula and solve for the equation
That's
<h3>We have the final answer as

Answer:
y=250x+300
Step-by-step explanation:
Let x be the number of heaters and y be the total cost.
We need to find the linear function for y in terms of x.
It is given that company can produce 15 heaters for $4050 and 25 heaters costs $ 6550.
It means the line passes through the points (15,4050) and (25,6550).
If a line passes through two points and
, then the equation of line is
The equation of line is
Add 4050 on both sides.
Therefore, the required linear function is y=250x+300.
