Answer:
y = x + 7
Step-by-step explanation:
Given expression:
y = 4x + 3
Coordinate = (8,5)
Unknown:
The equation of a line perpendicular = ?
Solution:
A line perpendicular will have slope that is the negative inverse of the one given.
Equation of a straight line;
y = mx + c
y and x are the coordinates
m is the slope
c is the y- intercept
For y = 4x + 3;
slope is 4;
A perpendicular line will have a slope of
Let us find the y-intercept of the new line;
y = 5, x = 8
5 = x 8 + c
5 = -2 + c
c = 7
the equation of the line perpendicular is;
y = x + 7
