The equation of the line that passes through the point (4,-4) and has a slope of -3 is y = -3x + 8.
<h3>How to find the equation of a line?</h3>
The equation of a line can be represented in slope intercept form as follows:
y = mx + b
where
Therefore, the equation of the line that passes through the point (4,-4) and has a slope of -3 can be found as follows;
m = -3
Hence,
y = -3x + b
using (4, -4) let's find the y-intercept.
-4 = -3(4) + b
-4 = - 12 + b
b = -4 + 12
b = 8
Therefore, the equation is y = -3x + 8
