# In Exercises 9 to 24, find an equation of the line described. Leave the solution in the form Ax+By = C .The line contains (0, 3) and is parallel to the line 3 x + y = 7 .

To determine

Find the equation of the line contains (0, 3) and is parallel to the line 3x+y=7.

Explanation

The general equation of a line is y=mx+b

Let m1 be the slope of the given parallel line

Let m2 be the slope of the line for which the equation to be found.

The given line equation 3x+y=7 can be modified to find its slope.

3x+y=7 can be rewritten as,

y=-3x+7

Compare y=-3x+7 with the general equation. Then,

m1=-3

Since the lines are parallel,

m1=m2

Hence,

m2=-3

From the given point,

x1=0

y1=3

Substitute x1, y1, and m2 in the general equation to find the equation of the unknown line
