Answer:
5y = -2x + 31
Step-by-step explanation:
Given equation:
y =
Coordinate = (-7,9)
Unknown:
Equation of the line perpendicular = ?
Solution:
The slope - intercept format of a line is given as;
y = mx + c
where y and x are the coordinates
m is the slope
c is the y-intercept
y =
From the given equation; slope is
A line perpendicular will have a slope that is negative and the inverse of this;
slope of perpendicular line =
Since y= 9 and x = -7;
So;
9 = + C
9 = + C
C = 9 - =
Now,
y = x +
mulitply through by 5;
5y = -2x + 31
