Answer:
7x - 4y + 18 = 0
Explanation:
The slope-intercept form of an equation of a line:

m - slope
b - y-intercept
========================================
Let

========================================
We have the equation of a line in a general form (Ax + By + C = 0)
Convert it to the slope-intercept form:
subtract 7y from both sides
divide both sides by (-7)

Therefore

We have the equation:

Put the coordinates of the point (-2, 1) to the equation, and solve for b :

multiply both sides by 2
add 7 to both sides
divide both sides by 2
[te]x\dfrac{9}{2}=b\to b=\dfrac{9}{2}[/tex]
Finally:
- slope-intercept form
Convert to the general form:
multiply both sides by 4
subtract 4y from both sides
