y=-x+10 is the equation of a line perpendicular to the givin equation using the given point given (8,2) and x = -4
<h3>What is Slope of Line?</h3>
The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
In the perpendicular lines the product of slopes will be -1
m1m2=-1
y=x+4 is the given line, it has slope of 1, so the perpendicular line will have slope -1.
The line is passing through (8,2)
2=-1(8)+b
2=-8+b
2+8=b
10=b
Hence, y=-x+10 is the equation of a line perpendicular to the givin equation using the given point given (8,2) and x = -4
