Answer:
Explanation:
Slope, m =change in value of y on the vertical axis / change in value of x on the horizontal axis
change in the value of y = y2 - y1
Change in value of x = x2 -x1
y2 = final value of y
y 1 = initial value of y
x2 = final value of x
x1 = initial value of x
From the information given,
y2 = - a
y1 = a
x2 = 0
x1 = 0
Slope = (- a - a)/0-0 = -2a/0 = 0
2) equation of the line is represented in the slope intercept form as y = mx + c
Where
m = slope
c = intercept.
To determine c, we would substitute y = a, x = p and m = 0 into y= mx + c. It becomes
a = 0×p + c
c = a
The equation becomes
y = a
3) y intercept,c = a
4) the slope of a line perpendicular to the given line is a negative reciprocal of the slope of the given line. Therefore,
Slope = - 0 = 0
