The standard form of the equation of a line is: Ax + By = C, where A, B, and C are constant coefficients.
We can use the point-slope form of the equation of a line to obtain this result.
y - y0 = m(x - x0), where m = slope and (x0, y0) is a point on the line.
Can you handle the rest, Keren?

Sorry, Keren. We know that the slope of this line is -4. That represents the variable
m in the point-slope form of the equation of a line. The line passes through the point (-2, 5). That point represents (x0, y0) in the point-slope form of the equation of a line. The rest is substitution and algebra. I'll get you started. You have:
y - 5 = -4(x - (-2))
y - 5 = -4(x + 2)
You should now be able to manipulate this equation algebraically to get it in
Ax + By = C form.
